Greater Grapple Monk Prerequisite

[Major Doom]

I noticed that Rapid Grappler has one of the prerequisites to be Monk level 9. I also noticed that Greater Grapple does not have a Monk level prerequisite, unless I missed it somewhere, maybe an errata or FAQ. I just want to confirm that this is true for Greater Grapple.

The "Improved" and "Greater" combat maneuver feats don't have any class-based prereqs. Rapid Grappler simply lists that you can take it at either +9 BAB or lvl 9 Monk (who would ordinarily have only +7 BAB).

Thanks for confirmation.
