One obvious thing would be that what was called "FSFSv7" back then
is now called "FSX". FSFS f7 today contains a simplified backport of
the logical addressing in FSX.

Completing FSX and stabilizing it will still take years - last not least
because the final shape of it is unknown. Without the split, we might
by now have a first rough implementation of all the (now FSX) features
that I had in mind last spring. It would still be far from stable, so
having *one* similar feature implemented and fully tested in FSFS
also helps the FSX development. More importantly, it gives users
sizeable benefits today.
