The rules haven't changed. Maintainers are doing the wrong thing. If a series is split up into multiple parts, then maintainers *must* coordinate to put the prerequisites into a single branch that can be merged into each branch handling it. However, it is still almost always better to just merge the entire series via a single tree.
Make noise whenever you see this kind of breakage because it means a maintainer has done the wrong thing.
