If the canonical location of base64 becomes Guile itself instead of 
guile-gcrypt, then it needs to be pointed at Guile's base64. Likewise, 
Guix' base64 implementation would need to be replaced by Guile's, with a 
fallback.

I don't see why we would point to Guix' implementation, it's missing 
some bug fixes.

Except for the remark about (1), I think so.  I think the following list 
is a bit more clear though:

 1. Add (ice-9 base64) to Guile (or another name (encoding base64)).
 2. Inform a few upstreams that used to include a copy of base64 that it
    is now part of Guile itself -- those upstreams can then remove their
    local copy and use Guile's base64, and do conditional module loading
    if they cannot increase their minimal Guile version yet.
 3. In Guix, we will have to update Guile to a new version that has the
    base64 module and remove the local fallback copies.  And if upstream
    refuses patches to use Guile's base64 (maybe with a fallback), then
    it will need to be patched locally in Guix.

On (2): I don't think it's necessary to contact _all_ the upstreams, 
though to give a good example it would be nice to contact some of them.

(3) is a Guix concern, not really a Guile concern.

Greetings,
Maxime.
