Shall updaters fall back to other updaters?

[Hartmut Goebel <h.goebel@crazy-compilers.com>]

Hi,

while working on refreshing to a specific version (see 
https://lists.gnu.org/archive/html/guix-devel/2022-06/msg00222.html) I 
discovered that the updaters fall back to another updater. Is this intended?

Concrete example (using refresh to a specific version): Package "xlsxio" 
has no version 0.2.30. When trying to refresh to this version, the 
github updater comes first and of course fails to get this version. Then 
the generic-git updater is triggered and tries to get the version.

IMHO each package should be handled by a single updater.

What do you think?

BTW 1: There are other packages which are handled be several updaters: 
If you sum up the percent valued of "guix refresh --list-updaters" you 
will get about 140%. Anyhow the generic-git updater contributed with 
about 30% to this amount.

BTW 2: Which updater is used for each package is non-deterministic.
