The other differences from I.380 were mostly minor, and Will Leland would enumerate them in the next talk. The idea is to not force individual values to be thrown out if they could be useful to create a distribution. This point was not judged to be controversial. ITU and IETF are trying to communicate, but the drafts seem to suggest they are from different planets. This talk tries to articulate and explain some of the differences.
Nobody wants multiple standards for the same thing.
Our goal is to have a clear statement of the area of overlap in concerns, and strive for consilience within that area of overlap. The T1A1.3 folks have taken pains to use some IETF vocabulary, e.g., host, link. Other terms have no correspondence. In sum, the differences are in what is explicit. The technical differences on loss and one-way delay involve notions that are missing from one or the other, but no notions are incompatible.
