Poking around, it looks like they may have done that because
parent.pm ("use parent" support) requires Tie::StdHash, and they
wanted that in the base installation.  It does seem pretty strange
though.  There is not much in perl-Tie:

$ rpm -ql perl-Tie
/usr/share/man/man3/Tie::Array.3pm.gz
/usr/share/man/man3/Tie::Handle.3pm.gz
/usr/share/man/man3/Tie::Scalar.3pm.gz
/usr/share/man/man3/Tie::StdHandle.3pm.gz
/usr/share/man/man3/Tie::SubstrHash.3pm.gz
/usr/share/perl5/Tie
/usr/share/perl5/Tie/Array.pm
/usr/share/perl5/Tie/Handle.pm
/usr/share/perl5/Tie/Scalar.pm
/usr/share/perl5/Tie/StdHandle.pm
/usr/share/perl5/Tie/SubstrHash.pm

I see the same division in RHEL9.  Don't have a live RHEL8
installation to check anymore.
