I don't like gating refineries and chemplant research behind setting up an oil pumpjack.
Currently, I automate tens of pumpjacks, refineries, and chemplants, along with necessary railway, then set up a refinery outpost somewhere with oil + coal + water in one go.
The new system would require going there once to set up pumpjacks to unlock the research, going back to your main base to automate refineries/chemplants, and then finally going back to set up the rest of the outpost.
We are aware of this. The gameplay changes, so you have to first acquire oil before being able to even start researching the infrastructure to eventually craft and build it. The concesus was, that it basically just adds a new constraint on the way you progress through the middle game, which can be part of the strategy.
For example, if you want to be efficient, you need to prepare a time when your factory can build what you need, while you find the oil in advance.
