disk_ident and gptid disabled in /boot/loader.conf

I wonder, why are the two settings below explicitly disabled by
default in /boot/loader.conf during 13.0 installation? I would think
it is better to use disk ids or gpt ids in configuration in case the
disks are moved to another port (instead of /dev/adaX, etc). One way
to encourage that is to make them visible from the beginning, meaning
installation, for new users benefit. I had to spend some time with
google to find how to make them visible, as there is some wrong
information online.

kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"

There must be a reason for them to be explicitly disabled by default.
What is it?
