We should obviously have no desire to take sides in Egyptian Parliament v Egyptian Prime Minister… but seeing as one such set of changes has already been released (in 2016e), from our standpoint, inertia should probably be a strong factor in our decisions here, where there is an absence of internal political consensus.

Since quite a lot of confusion is bound to be unavoidable either way, I think it's likely best not to introduce additional uncertainty and to sit on future changes until it is more clear what people actually do.  This would also help to keep any future advice in response to that confusion as simple as possible (e.g., "use $VERSION or later", "don't use $VERSION_A through $VERSION_B", rather than dealing with any number of possible intermediate and alternating states).
