RVA23 is actually a decent ISA for linux machines for the long term, RVA20 was not.

Presumably there's going to be some hardware releases later this year that Ubuntu has early knowledge of.

Does this line up with what riscv android will also require?

Yeah, the RISC-V community itself didn't see it as sufficient to build a competitive chip with until RVA23. The relevant milestones have been worked on for years. A LOT of effort was spent to get them right because ISA standards are hard to undo.

RISC-V has been perfectly suitable for embedded use and RISC-V is killing in that market.

But none of the Linux capable hardware produced up to this point has been competitive with existing alternatives. No one was seriously thinking that the OrangePi was a better value than an RPi.

These computers were primarily useful as dev boards to start porting software. The manufacturers are trying to scale manufacturing and establish market share, not turn a big profit. They knew their v1 hardware would be buggy and short lived. The CPUs themselves have been busy speed running the complexity levels that ARM and x86 had decades to develop.
