It's available in all layers, but as Tollef said it's manual. (In crypttab most likely, because that's commonly the lowest layer.)
You need to enable it in all layers (fstab, crypttab, lvm.conf), yes.

Ah, thank you for your explanations. But the documentation doesn’t sound encouraging. „man crypttab” gives a security warning and „man mount” says, this option is not sufficiently tested yet.
