Thermal time constants can only be ignored for far out-of-band signals like 'DC'. Since the discussion is about potential distortion products they are in play because they can cause IM.
Another area that can cause serious problems, especially for power resistors, is the termination where the metal with the deliberately 'high' resistance (and hence running hot and cold) transitions to the leads or tabs. I have some large resistors that I use for working on power supplies that have become virtually unusable from this problem.
