True.  Some things (like Sup2T) are worse than others.

LOL!  Yeah I wouldn't do that either.

Some people are more plugged into the beta and release process for the 
Nexus line.  I've been fortunately enough to do that for a number of 
features across N7K, N5K and the N1010.  When those features were solid 
during the beta phase, they were released appropriately and fairly 
quickly.  So, that's all I can say right now :)

LOL!  No.  But, I would say given the past with the 6500, I much prefer 
the N7K and think it's been a much more positive process.  Bug free?  
Absolutely not.

I'm not sure that edge N7K deployments are weird.  But, if you are 
interested I'm always willing to listen/learn about things people are 
doing with their equipment (or where new ones may fit).  Feel free to 
contact me off list if you want to chat.
