There is support / need for 32-bit pups. (I like 32-bit because they have a more consistent lib structure than 64-bit where multiple conflicting lib structures seem to exist)
I like incremental, small step changes in developing. The jump from Bionic to Focal would have been too big if I hadn't gone through CC, DD and EE first. Therefore GG would be the next step on the road to JJ 22.04. However it looks like 32-bit systems based solely on Ubuntu components have reached the end of the road with Focal.
Pups based solely on Debian or Devuan are probably the future for deb based 32-bit pups - but there are other DPup developers @josejp2424 & @radky who are better placed to take them forward.
Other possible non-deb bases have been mentioned. I looked at Void and it seems to have a package approach based on providing source in it's repos and then compiling/building binaries locally - this seems incompatible with Woof-CE which expects binaries to be directly available. I may be wrong?
So... UPupEF will probably be the last 32-bit Ubuntu based pup.
