What's the use, if the rest of the operations still use the buffer-local 
value of xref-find-function?

You'll get Elisp identifiers in completion, but won't be able to 
navigate to them.

The natural extension of this approach would be to have a 
project-xref-backend accessor, but do we really need that?

The same minor mode that enables your project globally could set 
xref-backend (the variable is still called xref-find-function, but not 
for long) in all buffers. It'll actually be a list, so you'll put an 
always-active element at its head, just like with project-find-functions.
