IIUC, this is due to the primary/secondary methods mechanism, which add
a prefix when methods are secondaries.

Last time we spoke about that, the consensus was to remove this
mechanism so there's not two ways of naming groups like you point out.
But we never started doing it mainly because it can be tricky to not no
break working setups.

Maybe that's time to do it.
