I guess I had the impression that the Linux FS layer already had

Unfortunatly, no. The linux VFS layer requires root (or CAP_SYS_MOUNT,
I guess) to perform the mount syscall. Even for tmpfs or union mounts
on mountpoints owned by the user.
However, the use of fuse-based filesystems and the (suid) fusermount
tool can emulate the behavior that is desired here.
