Do we still need the preprocessing steps?

• Should we remove the optargs for methods?

I would say for the native implementation it is confusing to keep the optargs.
I think the centralized vs native implementation is a very interesting discussion, and I could envision some reviewers being stubborn about us also testing the centralized preprocessing approach. Therefore, I suggest keeping the optargs in a separate branch, but otherwise removing them.
My 2 cents.

Sounds good & I agree. This is also linked to #333 on how we should trim the branches. Will mention it there
