Unless we do want to be able to switch next-error navigation sources 
this way?

Alternatively, we could uniquify the Xref buffers in a more predictable 
way (e.g. by using the caller command and the input string, somehow), 
and then have commands xref-searches-back and xref-searches-format 
switch between the resulting buffers.

What kind of support? Not sure I understand, sorry.
