Ah that is interesting. The spec has changed. My assumption is that they are trying to get people to move away from using chipselect on regular slave interfaces.

I normally do not use the chipselect signal as it's provided with "read" and "write". The only time I use it is when I'm actually interfacing to an external IC that needs the signal (even then you could derive it from read and write).
