I am curious how you would propose to resolve that taking into
account all existing packages and this detail that people making
original packages may be often unaware of the issue and even if they
are they may not have suitable installations for testing.  Multiply
that by 'extras', external repositories, and so on.  If you will get
strict here then resulting pains will surely far exceed your worst
current hiccups.

AFAICT dependencies are really "swallowed" during an installation if
files in question are the same - which is easy to test.  At least if
the whole concept is not buggy It appears that you were bitten by
something else or you run into some traps in testing but that what
testing is for.

There are obviously open problems in a multilib packages _removal_
but this is not exactly the same thing.
