Just to clarify my rather unclear message of yesterday, what I meant
was not that there were not good reasons for forbiding modifications
but that the reasons given in the proposal stopped short of stating
those good reasons in the rationale. But I was wrong because enough
of them are stated in the Problem Description.
Sorry. I wasn't thinking very clearly last night/this morning.
