Yeah, it would most likely affect my interpretations, though I hope that my artistic taste and integrity would grow just as much. I admit that, though I've not been one to think speed itself should be a goal, I myself have a tendency for my muscles to just want to be moving at their top speed. That physical urge isn't necessarily "interpretation" but rather just my own, personal, physical urge. At the same time, I can imagine there are beautiful, musical ideas which could be clarified should I become more limitless in any way at the piano, but that's not limited to the skill of just speed alone but pertains to less limitations in any skill at the instrument.
I recently observed an interesting master class with a young man playing the 3rd movement of the Appassionata, and the Teacher explained that the piece has nothing to gain by more speed, but rather to focus on the rhythmic integrity. Nothing necessarily earth shattering about that in and of itself, if you are a person who already accepts that speed is not the goal in and of itself, but still it somehow brought the idea of musical intent being number one, closer to home for me. For that piece, if the goal were speed, you could just have races and somebody could be declared the fastest but I see very clearly that it could potentially just miss the entire point of the music completely. I've always known this, but somehow this was more clear to me as a deeper understanding.
So, yes, breaking the perception of pianistic limitations (including speed) seems to fundamentally always be to our benefit, but so long as it serves a musical purpose.
