The holder of the latter view is confused. (does that count as religious?)

Seriously, what all the providers I have experience with have done is let
you burst to whatever the link capacity is and charge a premium on the
overage above the normal committed per Mb rate, or bump you to the next
committment level once you have sustained an overage for a period of time.
While it can make traffic engineering a little more difficult, both of these
represents a revenue opportunity.

If you take the first approach and charge a premium it has the advantage of
generally being self-corrective when you explain to the customer they are
paying more by not making a larger bandwidth committment. Taking the second
approach is easier for you, generates additional revenue, but could be more of
a billing/customer service hassle.
