Personally I feel Sigma's current strategy of selling the dock at a low cost is the best way to do it. It is an optional accessory, that provides extra user value in allowing more micro-adjust and AF options (depending on lens) if you need/want it. It is not mandatory to have it to use their lenses. If they supplied it with every lens, you could end up with a lot of them lying around unused.
On 3rd party licences, the only one I'm quite sure about would be Tamron since they're part owned by Sony anyway, and many lower end Sony alpha lenses are rebadged Tamron lenses. Then again, it's not such a distant 3rd party in that case... There is also the relatively active Sony-Zeiss relationship to consider.
