I don't know what you mean by "system specification", but I guess
that a lot of code assumes that variables declared with defvar (or
defcustom) can be bound fluidly.  For example, to write something to
a file with a specific coding system, one would say

    (let ((coding-system-for-write 'foo))
      (write-region ...))

where coding-system-for-write is defvar'd.  Constructs like this must
be ubiquitous in Emacs, I don't think you can "isolate" them somehow.
And since there are hundreds of variables in Emacs, what kind of usage
would be "typical"?

Does this help at all?
