I don't find the power of 2 thing particularly compelling when the
next point is 3072.  What might be more compelling is support for an
assertion that 2048 is more likely to cause the extension to be used
over the current arbitrary groups.

Otherwise, I'm all for having stronger keys.  2432 is an odd choice,
2560 might have been easier to understand, but more is better, right?
