For promise applications there is no problem with this; I am not sure however if that is an entirely representative use case. You could definitely imagine some invariants being broken. I guess that's why you have a `'toolong'` event

Exactly like with a script stuck in a while loop of sort (for which, we 
don't even have a callback to repair things. Maybe an extension to 
functions could allow this sort of mechanism for normal function calls).
For the vast majority of the code I have written, I think I count myself 
in the category of those who do not know how their code is broken by the 
"script too long" dialog.
As you say, it should be a rare case (as rare as the slow script dialog 
nowadays, I imagine)
