This should be a commandline option (e.g. --no-xtal), rather than uncommenting

Yes, agreed. This board is known to come in different variants on the 2nd hand market and I don't feel like removing the xtal to test things as my board has the xtal populated. I will remove this commented out code and leave the commandline option for a possible future branch.
