Yes. It is why I said the below.

Also, yes. It would be complicate more or less than one FS. And maybe I
can understand why you want to concentrate FAT.

But I'm afraid to implement for only FAT. If there is not any some sort
of agreement by others, it may have to re-implement. If that happen, FAT
can be bothered by compatible (or have to maintain both of old and new
for a while). Because the notified data are some sort of ABI, IMO.

This is why I'm careful about this, and can't say easily - "let's try it
on FAT".

Thanks.
