Said with tongue in cheek FH, but seriously, with a castoring nose-wheel, it should be pointed the right way at all times except when on the ground.
SDQDI, sure, little taps of rudder and brake needed to keep on runway BUT, if aligned correctly first, this should be minimal except in high X-wind conditions. Times when I don't fly. The amount of braking required would have very little influence on rolling speed. I do like your idea of some sort of independent pressure relief though. Will look into it. As for landing with brakes on, I'd expect a smashed nose-wheel leg for sure, then a slide on the forward belly. No engine to damage as it's a pusher.
Ain't experimentation fun. Keeps me off the streets as they say.
