I don't think any one has claimed "no one" needs to care any more. What the vfsmounts buy us that is that software that doesn't know and should't know about btrfs subvolumes isn't silently broken. Software that actually wants to do something fancy with them always need special casing. > Tools will have to change either way is my point.
