In my mind, Veilid (https://veilid.com/) is trying to solve this exact problem.
It’s only been public since the last DefCon, so it’s a little raw at the moment. That said, it is also only a framework - specific applications need to be built.

There’s this back story about the “LoongArch instruction system, a RISC ISA that blends ideas from MIPS and RISC-V”. The article says it is MIPS-compatible and even runs the same Linux code [Loongson’s] old MIPS-based CPUs did. Why not just use RISC-V? MIPS is licensed from the USA. I guess they have a lot of legacy people at Loongson.
