From a style perspective the carto port is incredibly close and pretty much good to go. It looks like the performance questions [1,2] that came up are more of a hurdle right now, others can speak more educatedly to this.

I was doing some poking around yesterday and noticed that county
borders (admin_levl=6) aren't being rendered at zoom 9 and 10. But I
do recall some confusion on the existing style between ways and
relations. I don't remember the details but there was some difference
between the zoom level at which ways and relations tagged with
admin_level=6 got rendered. Maybe this caused confusion when porting
to carto? Easy place to see this difference:
