Eh. Seems my brain has managed to filter that out thus far.
Probably as "uninteresting" is the only thing I can say :)

What is interesting is that in current vfat I can toggle
+x bit on and off with chmod. So it seems like VFS does
not consult with fs anymore about bits. But you know
that already.

Oh well...
