Which does not allow BC breaks but for extreme cases. I do not consider this case as extreme, at all. I share Nicolas concerns here. This is the kind of changes making the migration path harder than it should without a strong reason behind it. I agree with Nikita but it is something that can be solved using the depreciation flag and then handle in the next major. > and a dot zero at that*.

Obviously the sooner. And what is the next BC breaks for 7.2/3/4? This is exactly why we introduce the no BC break rule. In this case it is even more clear as one can use getName if desired to support 7.1+ only, which I suppose is most likely not the case for a large majority of users.
