And then you run into the customer who thinks it's better to use a CPE
of his own, breaks into the CPE to read your config and hooks up his own
device with his own config... and suddenly you have Problems[tm].

I've seen it happening, more than once.

Am I alone in my view that BGP is _far_ more simple and straight-forward
than OSPF (except in salary negotiations of course *G*)? Especially if
you leave "plain simple area 0". Or if you have to protect from external
parties. With BGP prefix-filtering, things are easy and obvious.
