I was mistaken here.  Lexical binding is briefly mentioned as
non-default behavior.

So why are we attempting to remedy this pitfall of the novice in Emacs
Lisp mode by inserting a feature hitherto _undocumented_ in our manual

I recognize this argument is grounded wholly on principle, but principle
itself is as important a consideration as any other.
