What is this? Users have to change their import statements just because we re-organized directories?
I don't think that is ideal

[dvreed77]

Only if they happen to be importing that far down from featuretools.primitives.aggregation.api

[rwedge]

Why is primitives.base being renamed to primitives.core?

Why is primitives.base being renamed to primitives.core?

WIll change that back, was getting a little trigger happy :)

[rwedge]

The idea behind primitives.standard is that if a primitive was in that module, it was one of the primitives that was part of the basic featuretools installation. Since featuretools.primitives loads in primitives from other libraries via an entry point, featuretools.primitives isn't a good indicator of that.

[gsheni]

@dvreed77 do we still want to do this or should we close this PR?

[thehomebrewnerd]

Closing in favor of #2331
