It's possible we've become accustom to a slow, global BGP, due to a 
perception of fragility (and complexity), which favours stability over 
speed.

I suppose the size of the current BGP and the nature of the FSM it lends 
itself to does some to account for those perceptions.

At a per-ISP level, it is not impossible to speed up (i)BGP convergence. 
On a global scale, taking the least common denominator to allow for all 
manner of network we don't know about, allowing the ship a wide turn in 
BGP waters, at least on a perceptive level, seems like an unsigned 
social agreement amongst autonomous systems.

Ultimately, I feel we aren't talking enough about this, and hopefully, 
this thread gets us to that point.
