Didn't you had problems with partial upgrades when moving the file from
one package to the other ? Or did you plan to add a dependency from bash
to dash ?

If that's really the only problem left, I think you are entitled to take
whatever decision you think is the best. Both approaches seem reasonable
to me.

Shipping in a package works but I wonder if you can still guarantee that
when moving the file from one package to the other without creating
dependencies that some people will dislike.

Well, that idea was based on the premise that we can't safely move the
/bin/sh symlink from one package to the other without risking loosing it
at some point.

It the premise does not hold true, then of course the whole idea is
