Sorry, I have been looking into manual about themes and custom.el; sure
theme can do anything so I understand it now :-).

"Custom themes are collections of settings that can be enabled or
disabled as a unit. You can use Custom themes to switch easily between
various collections of settings, and to transfer such collections from
one computer to another. "

".... loading a Custom theme can execute arbitrary Lisp code ..."

"To apply the choice of theme(s) to future Emacs sessions, type C-x C-s
(custom-theme-save) or use the ‘[Save Theme Settings]’ button."

So indeed  it can be used for anything. Though I would rather call
such theme for a "mode" but that would be really a confusion since Emacs
modes are different things.
