Is there any RDM bonus for Blue or Gold levels on A3?

I'm contemplating putting 20k miles into A3 for up to three (!) years of *G lounge access. Assuming I don't get any RDM bonus at any point, I'd be giving up about 20k RDMs (worth roughly $200 to me).

An RCC membership is $400/yr for a 1P and I'd need roughly 2-ish years worth of membership, so I'd still be saving about $600.
