If a checksum file becomes required then it really is not the job of the
package to build it. Instead dpkg should generate one and include it
automatically. And given the widespread generation of md5sum files that
really should be automated anyway.
This would go nicely with changing the checksum algorithm. Just prepare
a patch for dpkg to generate a sha256sum file automatically when it
builds a deb and then packages can stop generating md5sum files over
