As an interesting fact, windows totally supports mounting positions to folders and as far as I recall it’s been able to for a very long time, remember doing it as a teenager and thinking it was cool AF.

I think I did it back in xp, I was trying to figure out when support was added.
I don’t think it’s super advertised that it’s a capability which definitely doesn’t help its usage, heck I kinda forgot about it even though I used it until your comment triggered a memory.
