Yes! I haven't thought of a solution yet, not sure also if it would be better if the gap was smaller or bigger.
For Framework I would suggest to just create a trackpad with the full width plate, possibly with a few different alignments. It would be a loss for modularity, I do understand that.
Easiest solution would be to just shave the hair, I guess? :D
Oh, you mean the laptop frame and trackpad? Anyway, I've made a diagram.
