They still have different purposes, but sure, we can make an 
xref-with-doc element or something, which would render itself with a 
docstring.

That might be more complicated: a) the element would need to be 
specialized for the elisp backend, with type and plist, b) pressing RET 
in M-x apropos output does not get you to the symbol's definition; 
instead you jump between various Help buffers. I don't know if we want 
that for xref-find-apropos, that's certainly hard to generalize across 
languages.

The "search and replace" interface would have to be something like M-x 
tags-query-replace, at least at first. It's using a regexp, so people 
are probably used to confirming each replacement.
