Good points; in addition, I can only imagine the headache of trying to support the latest eBPF, io_uring, WireGuard, and other advanced kernel features in WSL1. I imagine a lot of newer features would return ENOSUPP from the kernel, so WSL1 basically becomes a weird fork of an old Linux kernel. (Weird because it lacks a large community, and old because the ENOSUPP's downgrade what's available.)

In WSL2 everything should work (depending on the CONFIG options and how much Microsoft has changed).
