The use for plasma in race is very limited and would see a lot more usage if you could do plasma ground boosts. If not implemented in pql itself, you could at least have it for race or as an option in SAM. The runs done in race would gain more variety and would make things a bit more interesting other than start from here, rj off of here, clip this wall, and rj off that wall.
To people that don't know what it is:
I definitely agree that plasma is almost never used in race. I haven't personally seen any situations where it is useful, maybe someone can point some out.
