Most of the functionality is present but many important bits are still being developed.

Thanks for the link.
a potential reason might be the very fragmentary nature of the RISC-V ISA, which makes a standard RISC-V kernel very complicated if you want to support more than a (barebones) profile. This is also supported by a RISC-V mailing list thread, where ‘expensive maintenance’ is mentioned for why Google doesn’t want to support RISC-V.
That might change. It wouldn’t be surprising if Google jumped back onto the train once RISC-V became popular again. But that might take a while.
