It would have been nice to have had some input at the time that what
little discussion there was happened.

I'm sorry, but at this point I'm of the opinion that the window for
discussing what license we switch to has been had, and the matter is
settled; those who didn't take part in the discussion have themselves
to blame if they don't like the outcome.

What I'm saying is that I doubt anyone has the stomach to go through
another set of license changes on the existing files to suit some
late-commer to the party.

However, we can't dictate to people what license they wish to submit
their work under; though, we can make the decision whether to accept
it under the license terms or not.

I think the problem will come if we try to mix a file that's licensed
one way, which includes files licensed under a different set of
licenses... if you want to use a file licensed under BSD 3-clause but
don't want to agree to the GPL license (so you're only bound by the
BSD 3-clause license) and that file includes some GPL/X11 licensed
files, then what?
