Please come forward with suggestions.

It's symbol lookup. It's a key feature that every IDE has had since the
beginning of time.

What is?

The sentences you're quoting are referring to the semantic difference between an arbitrary xref output (where we allow references that resolve to a buffer position lazily, as well as which don't point exactly to the position where the e.g. function name starts, but to the beginning of the line) vs. xref output containing essentially filtered results of a Grep search, where the positions of the beginning and end of the "match" are known.

It should work sanely in Emacs, and the fact that Eli has
had these experiences makes me think that the UI for xref is not ready for
release (by which I mean at this point: we don't document it or indicate that
it's present, until it's ready).

UI for xref, or just xref-query-replace?

Anyway, you're welcome to do whatever you think is appropriate.
