While I understand this position (and frustration underlying it), my
question wasn't entirely theoretical, so let me rephrase it in a more
pragmatic way:

If the data owners are setting the license for you, could they do so
with a more permissive license that's future-proof?

Otherwise, license changes are inevitable and we'd just be kicking the
can down to the poor saps who'll have to deal with this down the line.
Based on our level of committment to OSM, I'm afraid we're those saps!

So it's about a dataset of 1:1 building correlations and then another
dataset of 1:multiple and then handling it that way? So there will be
some "holes" in the intermediate?

I'm not suggesting that this is wrong, just want to explicitly
understand what's being proposed.

I agree with this view.

That would be awesome.

It's at times like this when I truly regret living in Washington, DC
for 16 years. I sometimes forget how to speak normal English.

You have dataset A released today. In a year or two you'll have
dataset B. There will be a delta between the two that will hopefully
capture new buildings, removed buildings, new addresses, etc.

I'm not even asking how to handle this delta from a community
standpoint (though that'd sure be nice) but rather just "Have you
tried to perform this delta and looked at the results?"
