As binNMUs get an extra changelog entry compared to their arch:all
counterparts, all approaches that try to make them equivalent seem
fundamentally broken to me. But maybe I'm just misunderstanding you.

I find this suggestion somewhat appealing, particularly as it would
remove the dependency loop that people frequently complain about
(#527917 / #502455) and simplify major version upgrades.
The size of the packages is roughly
package size installed-size
perl 5M 15M
perl-modules 3M 15M
so with ~15 architectures, the join would take on the order of 50
megabytes more mirror space per suite, altogether something like 200
megabytes. That does sound a bit much, but OTOH it's less than .1 %
of the total archive size.
A quick count shows 116 packages in sid that have a versioned dependency
(build- or otherwise) on perl-modules. Those would have to be fixed
first unless we provided a transitional empty perl-modules package.
In any case, the join wouldn't solve the issue this bug is about
completely, as perl-doc also has an arch:all->arch:any symlink in
/usr/share/doc. It therefore seems to me that a possible perl/perl-modules
join is a separate matter and should not necessarily be coupled with
this bug.
I think removing the symlinks with maintainer scripts and separating
the /usr/share/doc entries is the best course of action here.
