The industrial jobs may not be particularly well suited for being included in the urban job bundles, since consumer goods are used not only by other jobs, but also for pop upkeep - which is a function of living standards, traits, civics, habitability and other factors. The huge variability of overall demand for consumer goods means that it needs to be possible to adjust that output independently of the other jobs that use consumer goods, similar to how the three basic resources need to have separate resource districts rather than a single "rural" district.
Basically, I think there still needs to be industrial districts in the new economic model, covering consumer goods, alloys, and perhaps also synthetic strategic resources; the composition could be influenced by the zone and buildings. Re-adding industrial districts could also reduce the job pressure issue with urban districts.
