Excellent.

I don't know if it's necessary indeed (and as Juri notes, there will be 
another approach available).

We might consider it problematic, though, that for 
'project-query-replace-regexp' to operate properly the user needs to 
save all the buffers manually (they both need to know that they need to 
do that, and how to do that). Maybe xref-query-replace-in-results should 
have an option to save all touched buffers in the end. Or maybe 
perform-replace should have one.

Hopefully we can also resolve this difficulty another way, providing an 
inline editing mechanism for Xref buffers.
