"I want to specify things in this way, but not that way" is not a new, 
or a disregarded, requirement, as long as both ways are equal in 
expressiveness, and I think we've established that they are.

It's not like I'm happy to make things harder for you, but simply 
insisting on your side without addressing my objections won't improve 
anything.

Apparently we've decided to make both xref and project.el experimental 
in Emacs 25. It will be an opportunity to think on them more and collect 
more feedback, without committing to the current APIs.

+1.

You're unlikely to be able to rewrite *all* of ada-mode's 
project-related functions like that, but being able to do that for some 
of them will be a win already.
