Ok, fine. Please go ahead and implement the support in pkg_admin, and
we can then use it for checks as you suggested. It would be great if
this could happen before the next branch.

Independent of that I'll switch to the code after the
branch, without the extended syntax, then we can immediately start
adding license information to packages which are singly licensed
without any complications, which, I hope, should be most of them.

I won't add any user-visible warnings for missing licenses, except to
pkglint or when PKG_DEVELOPER is set.
