The downside to this, I think, is that it takes away the freedom to decide how important you want a consequence to be. The nice thing about the current system is that while you can decide to Compel that broken leg if you think it would be interesting, you can also ignore it if it would just be a distraction.

Then maybe the solution isn't mechanical. Maybe it's behavioral. Maybe just creating examples of consequences in play for games with different themes would be a better solution than changing the rules.

Medical treatment creates a maneuver aspect that sticks with the character.  They can tag the aspect to pay off a compel on an invoke of a consequence.  The quality of the maneuver must = the consequence.  Extra shifts(like every three shifts) could go towards extra tags

That does seem like a solution in keeping the theme of DFRPG, but I feel like if a good alternative to wizards con and recovery powers isn't put into effect beyond maneuver aspects, we'll just wind up seeing more people putting those into their builds.

How about first aid specifically, just a Scholarship roll with no stunt required, provides maneuvers like the ones discussed, but a character with a stunt related healing is capable of doing something outright better, as long as they have some kind of operating theater and tools? That would make the Stunt worthwhile, and could actually fit in with the stunt rules as is by providing a new trapping for Scholarship.

How about, instead of a full downgrade, a successful Scholarship roll + Doctor stunt reduces the time of recovery somewhat, but not as much as it would by reducing the severity of the consequence?

For example, a moderate would be reduced from lasting until the end of the next session to three or four scenes. Still significantly longer than a mild consequence, but much better than going without medical attention.

Actually, the 6th Law doesn't forbid anyone from looking into the past.  It just forbids anyone from travelling there to do something about it.  Postcognition is totally fine, as is precgnition.

Precog is sometimes treated as not quite OK in the books. However, that's probably because seeing the future kills mysteries faster than Sherlock Holmes with a time machine.

Is that a fur diaper?

I'm sorry, I've been arguing while under some misconceptions about the rules. I assumed that ambushes were 'free' whenever someone successfully managed not to be noticed by other characters, rather than being a trapping of a specific skill. I also assumed that evocation allowed skill replacement on the fly, which is definitely not in YS.

Veils are sometimes spells and sometimes not spells. And Stealth rolls are pretty much never spells.

If it's not a spell, then it's just an ordinary block or maneuver, not matter how many weird powers or declarations or whatever are involved. If it is a spell, it runs out at some point.

Regardless of the reason people don't know where you are...attacking them is going to give them some clues. And that's a good thing, because being hidden is really powerful.

Perhaps I don't understand what you mean by 'being hidden.' What mechanics are you referring to that allow characters to 'hide' besides spellcasting and the stealth skill?

That's also why I don't want to give automatic ambushes to hidden folks. It's too strong. And anyway, if there's a fight on their guard is probably up even if they can't see you.

Hidden folks do not have automatic ambushes. You have to roll to set up an ambush with the stealth skill, and that is going to be opposed by whomever you're trying to hide from. But some people could repeatedly ambush during a fight if they have a way to hide themselves even during combat, such as spending enough fate points or have an appropriate stunt/power.

A GM doesn't have to allow this, and can certainly houserule that this type of behavior isn't allowed, but as far as I know it's just part of the system.
