You, of all people, John, are very aware of my efforts on this basis.

I agree it's a very large if. In fact, the very real probability that dissatisfied customers will
use their ability to multi home and run BGP as a reduction of the pain point of changing
subscribers is probably the largest reason that it is not available. The providers have
exact opposite motivation. This is a fine example of how the efficiency of the invisible
hand fails when it comes to technical products where the masses fail to actually
realize that they are being shafted and artificially constrained by the limitations placed
on them by their vendors.

However, that's getting a bit far afield for NANOG, so I tried to stick to the technical
aspects of the argument.
