RVA23 is pretty nice. This is the first RISC-V profile that's really viable for desktop class CPUs. (But I still wouldn't buy a RISC-V chip expecting to run Linux on it until they have proper support for UEFI, ACPI, etc. and "unified discover" is specified, which won't be for probably 3-5 years.)

I hope those things will come but no need to hold off if the performance is there. UEFI, ACPI, etc. are really about the boot process. For SBC class hardware, having a device tree in the kernel works fine. Even Apple Silicon Macs use device trees (no ACPI).

On Apple Silicon, there is a project to add ACPi in software (firmware) so that they can boot operating systems that expect ACPi (like Windows). You do not need it for Linux.

Of course, dynamic device discovery and power management would be nice. Bit it is not a deal-breaker for me.
