It's not clear that that is the intention. This has been in the spec and
the design since the very beginning. You'd have to ask someone who
helped with the original spec to be sure of the intention.


It has always allowed for using any license. I suspect the intention was
for convenience and to provide some consistency for common licenses, eg
so we don't get packages specifying "gpl", "gpl2" "gpl-2" "GPL" and we
have to wonder if those are all the same. In the common case it gives
machine recognisable information.
