JVP,
That's a truism, and irrelevant to your point. Your accusation was that failing to use SPs means that systems are not performing to full potential. Are you now arguing that those with more than one customer need to create SPs for every backend used by a customer, rather than using a middle tier?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
