I've heard indirectly and off hand that some Microsoft PMs still regret calling it WSL1 and WSL2 instead of something like WSL-A and WSL-B.

My understanding from documentation is that WSL1 is "feature complete" but not "maintenance ended": they think they hit a strong Pareto Principal 80/20 for features in WSL1 and realize it won't support everything but often supports "enough" and any further compatibility issues are out of scope both because the tail is extremely long and the risk/reward of time invested into long tail issues are rarely worth it.

I don't think WSL1 will be "abandoned" any time soon, but the list of "Known Issues" will only continue to grow and a lot of people get pointed to WSL2 simply because the long-tail Kernel compatibility is hard to beat if you are directly running the Linux kernel.

But the many tools that work brilliantly in WSL1 still work brilliantly in WSL1 and there are still benefits to its barer/stranger metal approach.
