I would think that the suffix is not very important, and I have not heard
anything to the contrary.  If the user had access to two manuals in different
_locations_ but with the same name, then I can see an advantage in somehow
making the full file name evident.  (The file location is available in Emacs via
`pwd' etc.)

But I do not see an advantage in showing the suffix if there are two files in
the same location, one with suffix .info and the other without it.

I agree with Stefan - please elide the suffix in Emacs, at least.  That could be
done during rendering, if you do not think that makeinfo should do it generally.

indicated only the manual, now it shows also a file-name suffix.

Arguments saying, in effect, "but that _is_ the file" would be logically the
same if Emacs suddenly started showing the full file name ("path") in that

What is useful to users is the non-directory and non-suffix part of the file
name: "elisp".  Especially since the suffix has no special meaning: there are
not different Info-file suffixes with different meanings, AFAIK.  For users, the
suffix is noise.
