Main I2C SDA and SCL lines are currently connected with wires to Orangecrab

It was easier for me to enable extenders - you can remove those two wires bellow LCD - orange and black

I think according to the schematic these should be connected, but just weren't on this board revision, right?

those lines are connected to Xilinx - that was initial plan - later I just connected them with wires as it was easier to have control from orangecrab.

Modify the PCB to include these connections, provided we can be confident that no back-powering of the Xilinx FPGA will occur. We might need to have diodes on the Xilinx FPGA connector pins for this, to make the bus "read only" from the Xilinx FPGA.
