But what are you trying to say about the greater argument? The parent had two parts to it - make merging as difficult as unmerging, or make unmerging as easy as merging. While you're right that the wiggle room for making unmerging a lot easier is very constrained, this doesn't say anything about the feasibility of the other part of the 'or' and the actual argument they're putting forward. Unless you're trying to extrapolate this to saying that both these changes are impossible, it just comes off as being pedantic.
