I think at this stage the best is to add a note that it might fail when
used for lexical-binding code.

Agreed. Could you take care of it?

I don't think so. The programmer can reach his own conclusion based on
the text you'll add warning that some parts don't work.

No, that would be even worse, since some code only works in
lexical-binding mode (and there's no way to figure out if the code in
the current buffer is in this category).
