This has repeatedly been proposed

It breaks scm metadata and thus breaks build/install for quite some packages

Yeah we actually tried this before and had to revert due to packages relying on SCM metadata to build. I’ll close this issue. Feel free to raise further proposals if there are more concrete ideas on how to deal with the problem.
