Why is the BSD 1-Clause License not supported "out of the box" on FreeBSD?

I'm doing a full sweep of ports missing LICENSE and I continue
to have to jump through additional hurdles to represent the
BSD 1-Clause License in ports that use it. This has been puzzling
be for some time. So I'm asking. Why isn't it represented in
Mk/bsdlicenses.db.mk along with all the other BSD/MIT licenses?
Is there something in it that doesn't agree with the Foundations
policies? I've read the License Guide[1]. It's listed as OSI
approved[2] and it has an SPDX-License-Identifier[3]. Is this an
appropriate place to ask this question? Or is this something I
need to direct to core@ ?

Thanks for any insight on this.
