The list is usually very short (most of the time, only one candidate),
so the need for sophisticated filtering is quite low.

I understand.  It just seemed to me that, if we ignore for the moment
the features for creating/updating TAGS, what's left is very little,
and its contribution to the existing functionality is minor.  It
doesn't seem to justify a new package.

Maybe a better way forward is to extend etags.el with a few optional
features.

Anyway, these are just my opinions.  I'd be interested to hear from
others.

Thanks.
