They could be merged but devising logic and heuristics to do it
correctly would hardly be "simple".  In this particular case, they could
be merged, becasue the ':' label part doesn't have any properties
clashing with the 'index' name-of-parameter label part.  But in general,
that isn't necessarily so, and Eglot is a generic Eglot client, not just
catering to the rust-analyzer server which provides these very fine
grained labels.  So the simplest solution is taken and it is complex
enough.

So here the disadvantages outweigh the benefits.

Thanks.  This was key.  I've reproduced the problem (here, I didn't need
Mac OS) and pushed a fix to emacs-29.  The fix will appear in master
soon and thus also in upcoming Eglot 1.16.
