I wonder if x86 32 bit is still useful?
Many distributions no longer support it, and not sure if it is tested
througly by anyone.
Maybe time to deprecate it (gradually)?

It is used and tested in production and non-production environments.

Still used in certain memory constrained environments.

Distributions no longer support it for the kernel, but they certainly still
support running 32-bit apps. There's still a lot of code out there that
has not been converted to 64-bit, and we need to keep 32-bit DPDK around to
support that for some time.

Pure 32 bit, or x86-64 instructions and registers used in 32 bit mode (which can be faster).

Pure 32bit in our case. We do not use x32 ABI.

Same for our case.
