DEFAULT_VERSIONS+=perl5 does not work

[bagas]

Hello.
In /etc/make.conf indicated DEFAULT_VERSIONS+= perl5=5.32

grep 'DEF' /etc/make.conf
DEFAULT_VERSIONS+=  perl5=5.32

I'm starting to update the software installed on the server.
Why does perl5-5.32 start updating?

portupgrade -arR

Then what is this option DEFAULT_VERSIONS+= for?

Then what is this option DEFAULT_VERSIONS+= for?

To select default versions that are actually supported? ?

What's currently supported is always documented in the comments in Mk/bsd.default-versions.mk in the ports tree. For perl5, you currently find this comment.
