Other tech folk have always talked about 32 bit support as a necessary evil since smaller types mean less memory.

The complexity of managing a secondary 32 bit environment has been worse than the memory usage of 64 bit apps for a very, very long time.

If people want 32 bit pointers on 64 bit hardware they should pick the x32 ABI instead

That need has been met by the x32 ABI for some time now, it combines some of the best parts of the x86_64 arch with the lower memory consumption of 32bit (still limited to 4gb max memory though)

Will be interesting if a part of the community "forks" arch like they did for 16bit back then. However lowarch is apparently also dead by now: http://www.lowarch.org/ I still have that installed on a i386 machine, but not booted since years.

Did it even work usefully? While Linux itself retains backwards compatible drivers for a long time, X.org and others aren't quite as diligent.

E.g., five years ago I could not run any up to date distribution on Pentium 4 era notebooks with anything more than unaccelerated VESA framebuffers, because there were no compatible drivers for their integrated graphics card any more. (At the same time, we still had Pentium 4 servers in production use!)

One thing that concerns me is packaging desktop virtual machine images for easy reproducibility.

We realized that some users do not (or cannot, due to security policies) turn on VT-x/AMD-V in their machines, and therefore Virtualbox and VMWare Player cannot run 64-bit guests.

So we had to make 32-bit virtual machine images for them. If popular distros stop supporting 32-bit, we will have a harder time packaging such images, since we'll have to use a different distro for them, with different package names, settings, etc.
