What happens/ed in Ardour 2 is that whenever 2 regions overlap a crossfade
*OBJECT* was created corresponding to precisely the overlap between those
two regions. As the regions were moved or trimmed, the crossfade object was
adjusted to reflect that.

I have no plans to bring back this model. There is no crossfade object
anymore, and there is no notion of a fade between two particular regions,
only between a region and whatever else is below it (which could be 10
regions or could be silence).

Changing things so that when you first overlap two regions, the xfade of
the uppermost region is adjusted so that its length matches the length of
the overlap is ... feasible.
Tracking changes to the overlap caused by motion or trimming ... not
feasible (at least not for me)
