... last I checked, usrquota and grpquota weren't being propagated in, but that's changed sometime in the last, um, wow, has it been two years already? Perhaps I should have checked again before babbling nonsense to an audience of thousands, sorry!

None presently, but in general it seems strange to have to modify the kernel in order to be able to reliably associate some new key/value pair with a mount point, let alone to have to do it on a filesystem-by- filesystem basis...
