My responses were only about a separate boolean option for
xref-find-references.  AFAIU, that's not what you described,
disregarding the "boolean" part.

So, bottom line: which commands are affected by each option?  E.g.,
what about the -other-window and -at-mouse etc. variants: I guess they
are affected by the corresponding options?  Also, what other commands
are affected, in addition to the "families" of xref-find-definitions
and xref-find-references?  And what about stuff like
dired-do-find-regexp-and-replace -- is that affected by any of these?

Thanks.
