Is that really the case? I have trouble imagining that they are willing to drop support for rotational media quite this fast.

I don't know. I sure hope it isn't the case, we will need fast, optimized support for rotational media for a few years yet...

Optimizations for rotating media are not dropped. Some of the early SSD work was centered around detecting them properly, that gives you a way to make informed decisions on these optimizations.
