So it does not seem possible to form a 'swhid' as "swh:1:dir" and pass
'archive-type' as 'git-bare'.  And conversely with 'swh:1:rev' and
'flat'.  Right?
I have not tried though. :-)
If yes, it means the both arguments 'swhid' and 'archive-type' are
linked so the function should accept only one unifyied argument and
not 2 independent ones.  IMHO.

Well, let postpone the refactoring. :-)  However, if it works as I
understand, then the refactoring seems the correct way so I would not
accept a backward compatibility argument. ;-)

Have a nice week-end,
