Maybe dpkg should record the md5sum of the deb of each installed
package to prevent such accidents.

Look in /var/lib/dpkg/status:

The Origin specifies where a package comes from and is taken from the
Release files. Everyone should make sure to put the right information

else. Noone will do that any more than they increase versions on

That would affect a hell of a lot of things. You would have to change
the dpkg-architecture output for a simple change which in turn is
passed to cinfigure scripts and all hell breaks loose.
Very bad idea.

A comprehensive CPU-KERNEL-C_ABI system is in the works for multiarch
and it means extra work exponential with the number of fields and
entries. Adding useless, for the sake of dependency and abi cheks,
information in there as well would just blow up the work needed.
Very bad idea.
