Is that the only reason?  If so, why is that
a real problem?  And if it is, why is this a
good solution?

If you see some real problem of a particular
globalized minor mode interfering with Info 
mode, why not report that as a specific
problem to be considered for solving?

Emacs has already pondered this question, as
evidenced by the code comment.  It's still a
question, and worth raising.

But to raise it, there should be some (more)
information about what problems there might
be now.  Otherwise, `special-mode', here, is
a solution in search of a problem.

Info mode has been around nearly forever;
`define-derived-mode' has been around at
least since Emacs 20; and `special-mode' has
been here since Emacs 23.
