Intel Macs do, though; until Apple removed it. Worked fine in Mojave, but me (and many others) one day rebooted our Macs to find dozens of programs, libraries and plugins that no longer worked.

Whole thing sorta smells like Apple trying to further assert the dominance of AArch64, what with their insane stake in the ISA and it's eventual dominance. Not a terrible thing inherently, but the push to depreciate 32-bit hardware and software alike was pointless. 32-bit ARM can (and should) live alongside AArch64 as an ISA. From what I understand, the M1 even has secure 32-bit emulation mode built-in, without any OS functionality to leverage it.

Whatever Apple does, it's hard for developers to treat the Mac like a regular development target now. Besides the ISA change, the push for Metal-agnostic GPU pipelines has left developers scrambling. Massive open projects like Blender didn't even have an Apple Silicon strategy until Apple sponsored one. It's a bit of a mess, and kinda tragic that Apple is pointlessly complicating cross-platform development.
