I would prefer calling it "pil", because the text is different.

Unfortunately it seems that OSI/FSF are not actually approving these
variant licenses as Open/Free.

I wonder if you have checked if this license is within Debian main.
There is, while not documented for pkgsrc, a third body that in effect
approves licenses, in this case Debian which evaluates if they meet the
Debian Free Software Guidelines.  I would be fine with adding "approved
by Debian as meeting DFSG" as third way to allow licenses in

While I really don't like pkgsrc being in the business of approving
licenses, I won't object if you put this in as pil and add it to
DEFAULT_ACCEPTABLE_LICENSES, because I can't make an argument that this
license is not Open Source or not Free.
