Well, I'd like to primarily develop on the -mmotm tree as it fits in a
sweet-spot where the mainline is too slow and linux-next is too chaotic.

The bug was reproduced and the patch was tested on -mmotm. If for every bugs
people found in -mmtom, they have to check out the corresponding sub-system tree
and reproduce/verify the bug over there, that is quite a burden to bear.

That's why sub-system maintainers are copied on those patches, so they can
decide to fix directly in the sub-system tree instead of -mmotm, and then it
will propagate to -mmotm one way or another.
