Actually, it was as recently as this very week! Running with all the
latest updates on a new Surface Book 2, I ran into a variation of
this open issue: https://github.com/Microsoft/WSL/issues/1982.
Well that stinks. I'd swear I hit this and it got resolved with the inotify-related patches, but clearly I misremembered. Might be thinking of uwsgi or something.
Re. Hyper-V: yeah, I do a Samba mount. This in my experience actually performs a ton better than VirtualBox shared folders, but it's been a long time. I have no idea how it compares to VMware's implementation. (VMware and VirtualBox also have the ability to cleanly virtualize a graphics-accelerated Linux desktop, which is not something I need or care about, but might be a show-stopper for both WSL and Hyper-V if you do.)
