In this case I simply wanted to make sure, that people could include it
in projects, whose other dependencies are still stuck on Guile 2.0 or
Guile 2.2 in Guix.  Not really a "clear use case", but that's my
reasoning.
On the topic of those variants, however, would it perhaps be wiser to
make this a package-mapping instead, or is there a case where `--with-
input=guile=guile@$EFFECTIVE_VERSION` would be ill-advised?

I thought poking into Guile's backyard was a best practice in order to
get the attention of Guile maintainers, as with guile-readline and
guile-colorized ;)
My plan is also to contribute it to Guile proper at some point and then
perhaps keep that repository as a backport for a while until all
relevant versions of Guile have a "proper" filesystem module.
