Me, too.
I was thinking through some of the implications of this decision, which I think the COFC got right.
A proposal revision would only include changes to the part of a solicitation response that was binding (i.e., the proposal).
If that's true, then changes made to the part of a solicitation response that was not binding (i.e., information) could be made without discussions.
I don't recall the GAO ever making this distinction in clarifications v. discussions cases. Do you?
