FWIW, we are maintaining an x32 port in Debian and there are some people
actually using it . There is one build instance running on VMWare that
I am hosting  and around 10800 out of 12900 source packages build fine
on x32 (12900 being the number for x86_64).
The port is mostly stable but the fact that it's a 32-bit target with a
64-bit kernel API often blows up in people's faces because they don't
expect things like a 64-bit time_t on a 32-bit system.
The port also has some issues with software unaware of the x32 and builds
fail when they just test for __x86_64__ but not for __ILP32__, but overall
it's usable and stable and has some performance advantages over x86_64.
