Personally I think the kata teach us certain 'lessons',

In actual application we do what we need, it might happen in kata order, it might be one movement, it might be one movement from one kata and then another movement from another kata.

we might get hit a little bit...........or even break our 'perfect' posture!!!!!!!!!!!!!!!!!

I think the term 'free from the kata' comes to mind here, and it takes a fair bit of training to get there,

It also takes a fair bit of the right combination of trianing to get there.

kata alone is pretty................useless.
