I'm not quite convinced.  Service providers are interested in one thing,
being profitable.  Their revenues come from their customers.  Since running
a PTR has clear non-zero costs, the provider should be able to see some
offsetting revenue or strategic advantage.

The theory proposed above seems based on the fact that providers want to
attract traffic.  I infer that the thinking here is that more inbound
traffic would help offset unfavorable traffic balances, which would be
helpful for peering negotiations.  In the case of customer traffic
approaching a PTR, this would seem to be no different, as the traffic would
be arriving at the ISP anyway.  Thus, the benefit would seem to be for
non-customer traffic.  However, for non-customer traffic, the PTR would
encapsulate/decapsulate and hairpin the traffic back outside of the
provider.  In effect, this gives a way for the provider to attract new
traffic, both inbound and outbound, and not receive revenue for it.  While I
can see that it might be of interest to some, I don't see the broad appeal.

Real operators should correct me if I'm off base.
