No, this is a very unsafe default because benign `mount -av` will create more
layered mounts on every invocation.
Mount should be idempotent by default.

Not really. FYI attempt to mount ext4 for the second time comes back with
"already mounted" error and exit code 32.
IMHO mounting over non-empty folder should be only allowed with explicit
"force" option such as "-o nonempty".

Too many problems with that. First of all some software must be re-compiled
to remove "nonempty" option. Secondly, that makes file systems unsafe in
regards to `mount -av`.
I wonder what FUSE3 developers were thinking when they did such unsafe
breaking change? :( :(
