The teaching I received : gently lean forward, with a straight back, slowly come back and feel the hipbones section ‘hook’ the cushion and allow the subtle swing of the pelvis, is the primary teaching.
The mother of all teachings.

Presumably not so much « sit down and rock back and fore » as « be aware you are sitting and rocking back and fore ».
In which case, your « primary teaching » would be « be aware »?
