What would be the difference with 'make doc'?

In any case, a new Guile release series doesn't happen every
second day, and if we want to switch to a new one, there
should definitely be a mailing list thread where all details
of the transition are discussed, including how sure we are
that it works. For example, to switch to Guile 2.2, there was
a dual release and we removed Guile 1.8 support once it had
seen some use without major problems.
