It's maybe not dumb to use the forbidden internal symbols, but it's certainly dumb to go ask the folks who through naming and documentation have communicated almost comically loudly and explicitly that they don't want you using the symbols if it's cool if you use the symbols.
You would be surprised about how many times I've seen the internalVariableDoNotUse symbol to be exposed on the formal API of a library because everybody uses it already, it would be too much work to change it.
