Depends. For a home user who doesn't care about fonts, it doesn't. For
someone who cares, it does. If I am interested in some information, I
don't like if I can't get it just because someone couldn't imagine it
was a problem.

I don't understand this. Since a font doesn't "do" anything, but
software using the font does, one could write a rendering engine which
gives feedback about how well it could complete its job, and a
typesetting application might elect to make use of that feedback and
provide a notification dialog or whatever. BTW, as the information about
available glyphs in a font is independent of character encoding, I don't
see the relevance of this whole discussion to this list.

That's no reason. Just because many people don't need a feature, or
maybe just don't care enough to complain, doesn't mean it shouldn't be
provided for those who do need it.
I could well imagine that in a typesetting application, it would make
sense to be informed on whether a certain typographic feature can or
cannot be applied. Carefully checking a long document for whether, e.g.,
a certain pair of glyphs does form a ligature where it is supposed to is
tedious and error-prone if done by a human, but such routine tasks are
what computers are good at.
