No question about it. Either a flag or a completely different set of commands, you won't get any nasty surprises.

Long press can't be used. It is officially "help" when the command is in a menu. But the autocomplete feature would take care of all the different variants.

There's no reason why these couldn't be included, I suppose. Will you have multi-valued logarithms as well?

There would have to be a limit on the maximum number of simultaneous paths to be evaluated. These functions would have to return up to a maximum number of solutions to avoid eating all the memory.
Let's say you want sqrt(sin(0.5))
SIN(0.5) would give you the maximum number of solutions, and then sqrt would try to double it. We'd have to discard half of the solutions, but which half?
It would make it useless, as the user would never know which solutions are missing from the list.
Perhaps we should limit to solutions within the first turn in the circle.
