They stated that at the start of a large public playtest. They entire point of the public playtest is to see if players like your design goals and rules. Changing your goals and rules is the entire point of the playtest. If they talk about something at the start of the playtest and don't end up including it in the final game, it is probably something that most players didn't want.
I also think you are reading way to much into the original statement. I can play a simple champion fighter with no feats, where you just do a basic attack every round, or I can play a battlemaster fighter with lots of feats and have a character with lots of tactical options. They seem like a rules-lite OSR character and a 4e style character to me.
It's not like they gave a lot of detail when they first talked about it. It was litterally a couple of sentences in an interview before the playtest even started.
