@ValarDragon what's the status of this PR? Are you planning to continue? I can also take over!

[ValarDragon]

I think this is going to be significantly easier to rewrite with #1008

[mattverse]

agreed, lets try pushing forward #1008 and then revisit this

[ValarDragon]

yeah, no need to even get this PR merged, at most look at it for inspiration imo

[mattverse]

Closing this PR in favor of #1070
