But the filesystem integration is much better than a VM in macOS, being able to run Window programs from Linux, etc.
Also, Windows has decent X11 servers that work well with retina displays, which can't be said of XQuartz.

Many times in WSL2 I've had a git rebase fail because it couldn't overwrite existing files, and every time it could be fixed by just running git rebase --continue. The actual problem seems to be that WSL2 system calls return before the NTFS operation completes, so quick successions of create-after-unlink or write-after-rename can have unexpected results.
For this reason I still keep a WSL1 environment, it doesn't have the same issues (and doesn't appear to be any slower for filesystem operations).
It's definitely a great deal slower for filesystem operations inside the Linux system. Filesystem operations outside the VM's disk image go through 9p, which gives you basically the same performance for both.
Ack on XQuartz being crap (thought it does have Retina support these days, at least for non-rootless mode), but this is not really a problem of the VM.
Example: I type code ./somefolder in WSL and it opens VSCode on Windows, editing the folder I specified.
Edit: danieldk replied just before me, but I think my answer adds to that instead of just duplicating danieldks.
Also danieldks answer highlights something important: it doesn't seem to be just magic shell wrappers (or if it is they are truly magic).
VSCode is somewhat special when it comes to editing files, Notepad is not.
Whoops, typo. Windows programs from Linux, I'll fix that.
You can mount other host filesystems from inside the VM in any hypervisor I know of.
In most hypervisors you can't do a
notepad.exe foo.txt
TextEdit.app foo.txt
Isn't that just a binary loader, like you can do with wine/qemu on any Linux? Surely it's mostly just proxying the pipes, replicating the working directory, and maybe keeping some of the environment variables. The filesystem integration seems like the trickiest part of that altogether.
