It's been a bit since I've looked at license.bbclass, but I guess my
question here is this seems to take out all notification that a recipe
doesn't have a LIC_FILES_CHKSUM, correct?

I'd rather we maybe kept the note in and maybe whitelisted recipes that
did interesting things so that didn't appear than just ignored when a
recipe was missing it. 

Because if we don't at least bb.note it, I can see people just ignoring
it entirely (which would be bad in a lot of ways)
