In this example, I'm remapping by key and filtering by state. No I want to filter by attr containing a specific value and I might remap using something other than Key and filter on a new field I might add in the future.

I already have DataBy which allows me to map by anything that is of type string. How do I generalize HasState/hasState/filterData?

I'm trying to get [this](#1244717652568440873 message) to work in the overall thing.
