I'm reading between the lines a bit to try to answer, so if I missed your question or your intent please just point it out and I will adjust my answer.

32-bit is extremely useful. For intel, 16-bit is also very useful. The problem is that there is a strong divide between the people who find 32-bit and 16-bit useful at Intel, and the people who feel a need to force everyone onto UEFI "Class 3+" [1] and that everything else must be squeezed out, shamed, and moved to an emulator.

It sounds like Arm 32-bit support might be around for a while. I mainly wanted to clarify that Intel is dropping their 32-bit and 16-bit support.
