Indeed, bug#70136 solves many problems.  Using dir-local variables
in non-file buffers will for example fix such cases that when
need to add the "-a" switch to ripgrep to find files that
accidentally contain a null byte, then I see no other way
than to do this on per-project basis by adding to .dir-locals.el:

((nil . ((xref-search-program-alist
          . ((ripgrep . "xargs -0 rg <C> -a --null -nH -e <R>"))))))

But currently it has no effect.
