Yes. "Lexical" is too long, considering its relative lack of
importance. Space on the mode line is precious, particularly when
running Follow Mode. Also, "Lexical" isn't really a minor mode, so
shouldn't look like one.
How about, instead,
(Emacs-Lisp/L)
or
(Emacs-Lisp/D)
? Even that is going to be a nuisance to some people, so it really
needs a user option to turn it off.
