Would the coloring/DD algo on the outside be the same, just with a
different assembly kernel?
Or are you looking a fusing th
We are interested in assembling point-block diagonals for use in
pbjacobi smoothing. This is much simpler than AIJ, but lots of people
will need AIJ so it's certainly worthwhile.

Is there any plans/interest in assembling AIJ matrices on GPUs?
I have a somewhat strangely balanced FE operator and I have each thread
block create one element matrix, one thread per integration point with an
expensive computation at each integration point. Then I assemble the
matrices on the CPU
