Sure, It was not contentious, Given the Bips 70-73 luv2drnkbr provided. I was wrong.
BIPs 70-72 didn't exist until July 2013, and BIP 73 did not exist until August 2013. The thread I linked to was from 2011, and IP transactions were actually being removed before then. The removal of IP transactions was completely non-contentious even without the existence of BIP 70 or anything like it.
So maybe the definition of "contentious" is contentious enough.
