Here, Stefan Monnier will correct me if I'm wrong:

Lexical scope is better for general purposes and the
Joe Elisp Hacker, and this is illustrated by the fact
that >99% of the Emacs code that is dynamically scoped
would work just as well with lexical-binding.

There is no contradiction between text and
programming! And there is no hierarchy what is Emacs
primary, secondary area and so on. From programming,
Gnus, ERC, and Emacs-w3m, to writing love novels - it
is all on the same level.
