    Most? I don't think so. Small and simple apps generally don't, bigger
    and more sophisticated ones generally do. Apple's own apps are more
    likely to have provide services, but many non-Apple ones do, such as
    Emacs (duh), LaTeXit, Opera, Quicksilver, Skim, Skype.

"Provide services" is somewhat cryptic.  Which services does that refer to?

    Relatively few apps have the capability of sending user supplied
    Applescript commands to other apps, but I would suggest keeping that
    capability, since it strengthens Emacs' position as a useful tool on
    the Mac. (Though one could get much the same functionality by running
    osascript as an external command.)

It seems to me that this is precisely the sort of thing we should avoid,
since it is a feature limited to a proprietary system and not even most
programs on that system have it.
