I have trouble understanding your post, since you mix notions about "core" and "CPAN"

"core modules" are bundled with your Perl distribution, it doesn't really matter if they have XS dependencies since Perl itself is compiled too.

They are not installed via CPAN (only if you desperately need an update and wanna risk inconsistencies) and they are maintained by P5P.

Tho surprisingly is "core" not listed in perlglossary
