MSYS2 can do something better than Cygwin.

I'm disappoint to "VM-like" behavior too, so I don't expect they would be totally replaced by WSL.

But this is similar in the other direction. Many applications just rely on such "VM-like" behavior, even though they can be (re)built for Win32 and/or they do not need a real VM for functionality. Note WSL1 can already do something more, e.g. hosting programs as X clients working with VcXsrv. I don't think WSL2 will be necessarily better than WSL1 in many of such cases. (In particular, when I have to reserve VT-x for some other hypervisors, I have no other choice.)
