Okay. I would still refrain from calling these things by the class of the object consuming them. DMFormFunction() and DMFormIFunction() seem fine, since these have a meaning independent of TS (although the DM has to then encode a transient problem).
The IFunction is a particular way of representing a (part of) a transient problem. Its arguments include the time and the time derivative. We have to make that clear somehow and I think naming it after TS is helpful. Otherwise I'll eventually just have a bunch of names (function, residual, rhsfunction, objective, gradient, jacobian, ijacobian, hessian) and not know which ones go together.
