Itís *extremely* common. Iíd say itís the most common way transitions are used.

IMO it would be very useful to allow this in transitions as well and would open up some very interesting possibilities that require hacks today.
One solution that minimizes (but doesnít completely eliminate) the backwards compat consequences would be to make `all` mean all properties, but redefine the initial value to a new keyword that means "all interpolatable properties". Since most authors use `all` implicitly, that would prevent most cases of breakage.
