If you stick to "graymode" or the color modes (outputs R,G,B) it should be fine: there is a bug that clips large signals to 1, which is really a bug but has potentially been incorporated in many models. Certainly if you keep the sum of values to 1, it should rarely cause a problem.
For HSL, yes, there may be a problem... but I'd be surprised if it is related to filmic. If you want to do non-linear colour things, I'd suggest colorcorrect. The question really is what you want to achieve.
