In the case of define-minor-mode, the use of interactive-p (which
I tend to dislike) only has "trivial" impact: it is used to decide
whether to output a message and whether to consider the change as
"explicitly asked by the user so custom can consider it as a
user-customization".  This last difference has no impact whatsoever
as long as you don't use custom.

So I think using interactive-p is OK as long as it's only to
record some info for customize the use later, but it's not OK if
it actually changes the behavior of the command when it is
invoked.
