I'm familiar with those agreements too. Some of my opponents play them.
I play something along these lines too - Responder either supports or relays. That does not mean I would not take advantage of the option of showing a great side suit if playing 2/1. If you do play a method in which Responder cannot show a side suit before supporting, I suggest using a follow-up structure that allows Responder to show the side suit after showing support, or even going over to Fit Jumps outside of competition if the alternatives would be too complex.
