I believe this discussion is not about dynamic
binding as such; it's about having the default
be lexical binding.
That is, it's about having, by default, the
behavior you get with lexical-binding=nil.
That doesn't prevent any use of dynamic binding.
What it does is make Elisp behave like Common
Lisp wrt lexical/dynamic: It makes lexical
binding the _default_; nothing more. To get
dynamic binding for something you need to tell
Lisp that it's "special".
And yes, everything you said about dynamic
binding is correct: it is extremely useful, in
particular for an application such as Emacs.
But wrt that there should be no special need
to refactor anything. The problem (need for
rewriting/refactoring) is code for code that
expects or depends on dynamic binding by
default.
Long ago RMS summarized the special advantages
dynamic binding offers for an app such as Emacs:
