I know. Initially, I thought it will be necessary to upgrade Pod::Parser
without breaking build-root, but it turned out it was not necessary.

I think it's not possible to bootstrap dual-lived core packages without core
perl sub-packages. Mainly because they are not written in the way.

One could split scripts from libraries which would help at least with
Pod::Usage, but I believe it would not fix all issues. Therefore I'm not
going to deal with breaking cycles in these packages. (Bootstrap on next
rebuild will enable dual-lived perl sub-packages, then it will rebuild
standalone dual-lived packages, and then it will disable dual-lived
sub-packages again. Therefore I guard the sub-packages with perl_bootstrap.)
