Yeah, you weren't going to win this. Most developers I've met would have approached this from one of the two extremes:

"Lol, this is the obvious implementation."

or

"Lol, just use a boolean."

That is to say, those that might be interested would already know. I'd expect very little in between.

Fwiw, I do think noticing the id readability is notable from a reverse engineering standpoint.
