Even as someone who hasn't compiled a kernel in a loooong time (10-12 years?) this is a weird position to me. AFAIK Loongson's ISA is some sort of superset of MIPS64. Not exactly ubiquitous but MIPS64 has been around for a while so I would expect bootstrapping to be fairly simple. Of course, bootstrapping is not the same as, say, using the parts of the superset that help with x86 emulation to speed things up, but even QEMU has supported LoongArch since 7.1 (over a year ago.)
