I don't think we should bother about it.  Potentially, there always may
be some packages in ELPA that are kept there just for backward
compatibility (i.e., for the older versions of Emacs).  I really think
it is unnecessary to keep track of such packages and treat them
specially on the Guix side.

OK, I see your point.  I have an opposite opinion: I would definitely
check if a package is a part of Emacs before trying to package it.  And
I think 'let-alist' should be removed, since it is a useless package.

Anyway, if other people will not answer, I think you can do whatever
seems appropriate to you.
