Maybe so, but you just made the argument for doing nothing different in
current eapis and proposing stripping empty directories in eapi 7.
However, this should be stripping empty directories combined with
failing the emerge.

The issue is that if an upstream build system creates a directory, then
the upstream software tries to access the directory without creating
it, there will be runtime breakage.
