Comment (by ryandesign@…):

 Replying to [comment:9 mojca@…]:
 > We are not talking about perl5.8, but about two versions at most (at the
 moment that would be perl5.22 and perl5.24).

 But removing old perl versions (i.e. removing old perl version modules and
 old perl version variants) breaks user systems in confusing ways as
 reported in #51498. If we want to make a habit of removing old perl
 versions we'd want a solution for that situation.
