Well what's it to do? If you have one package dependent on 5.28.2 and another one on 5.30.0 then it has no choice.

Perhaps what would be preferred is that it stops any install and tells you that the package needs 5.30.0 and you have installed 5.28.2? That would seem more logical. That way it will refuse an install until you've updated to 5.30.0.

Well that's a problem with perl, surely. After all, how are you to have two or more versions of perl co-existing when at least one must be symbolically linked to "perl"?

 From afar it didn't break both, it just failed to add a softlink. Is that not the case?

Well, nobody here will unless the maintainer for perl is active. If you want this looked at, I suggest contacting the port maintainer and/or raising a bug report.
