So I opened the TAC case, went through the repro multiple times, 
documented it, webexed it, discussed it.

First I am told that there is an undocumented command to turn it off.

The feature we are talking about is  route refresh capability

this is a bgp hidden command which will not negotiate this capability 
and you will have to manually refresh routes after making any 
configuration changes.

neighbor x.x.x.x dont-capability-negotiate enhanced-refresh

Which does not work.

Then I am told that all IOS have been updated to do this and that there 
are no publicly available release notes for this change and if I want 
any further help, I need to have my account manager convince them that I 
am worthy.

Which seems to be the way they try to resolve all cases these days.

Cisco support has sunk to new levels. You end up paying them to 
sadistically torture and tantalize you. Which I am not into.

I remember when they would actually file a bug when you found one (with 
a mtrr +-2yrs).
