I still need to come up with a plan to add this with the least amount of disruption, maybe starting with opt-in.

Thanks @BuzzCutNorman! I'll take some time this week to go through this and #2259 to see where it makes sense to split and have a reasonable package layout.

@edgarrmondragon I am thinking it is time to close this PR since you have two very good PRs in the works and to be honest this PR is a bit of a mess. WDYT?

[edgarrmondragon]

I'm happy to close but give you proper credit in what ends up getting merged. Thanks @BuzzCutNorman!
