What I thought they were going for was that phones would no longer come with cable+charger, instead you could buy the one type of charger + cable that exists.

This would mean one connector for all devices. If they allow different connectors on phones then lots of different cables will be made, and when a person switches phones then their old cable ends up in the trash.
