Sure, unless they tell users what the behavior is
and users choose to use them, i.e., choose that
behavior.  An "application" can present choices to
users just as much as a user option can.

The function `customize-save-variable' is an
"application" that a user can use to change, i.e.,
override an option setting.  What makes it OK is
that the command tells you what it does, and it's
up to use whether you use it.

Good to hear.  But why the restrictions for non-standalone?

What I said about Icicles is independent of a standalone
minibuffer frame.  There are lots of situations under which
minibuffer content can reasonably be more than a line or two.

I don't see any good reason presented for such restrictions.
