I understand.
Org commands could get slowly or speedy adopted not to be shown in
other modes by using the recent development of the command
`interactive'
interactive is a special form in ‘C source code’.
(interactive &optional ARG-DESCRIPTOR &rest MODES)
If MODES is present, it should be a list of mode names (symbols) that
this command is applicable for. The main effect of this is that
‘M-x TAB’ (by default) won’t list this command if the current buffer’s
mode doesn’t match the list. That is, if either the major mode isn’t
derived from them, or (when it’s a minor mode) the mode isn’t in effect.

That may be said so, though I see that rather as neglect by design and
lack of checks. If we speak of functions that are not interactive,
your statement applies.
If we speak of interactive functions, they are accessible to users,
they should not be if the function does not apply.
M-x org-agenda-Quit -- it is good example, why have a function that
quits and leave it to user to invoke it in any other mode?

As you can see the `interactive' function already has that
functionality.
