Is it "frowned upon" in whatever capacity to, when a user asks a question about asymptotic complexity analysis of some algorithm, suggest implementation-dependent improvements, should the user potentially wish to implement the algorithm?
E.g. I responded to Is there a way to find path length to a node from root in a binary tree? with "If whatever language you plan to use to implement this should have it as a feature, you should take advantage of tail-call optimization. It would reduce your space complexity to O(1) (while still making a simple solution with recursion)" and had my suggestion addressed by a mod as irrelevant, hence my asking here.
