whether Rafael is right or wrong here, I haven't looked at the problem

This isn't going to bring you any good will. We don't care what was done
before it was a public project. That has strictly no relevance to how it
should be submitted upstream.

How long the code has been simmering internally to company X or Y or
even in a public tree doesn't matter. Some times, yes, we do take
something as a whole, when it makes no sense to do otherwise (a driver,
a filesystem, ...). 

But something like what you propose, it seems, could easily be broken
down into a basic concept, on which features are added one after the
other, and in this case, it's the right way to go, simply because it's
easier to argue for the basic concept alone if you don't have to handle
comments froms people who don't agree with aspect A B or C of the other
features involved.

And if the basic concept doesn't get accepted in the first place, then
the whole point is moot...

Cheers,
Ben.
