Synth blood could be a game changer but I'm wondering if they are going to make just a synthetic type O or are they going to try and go deeper to match phenotypes?

Made laboratory-grown red blood cells "0-negative type" would be all that we need.

Most likely much deeper. Here is some more info on the deeper types that you mention. Essentially, there are slightly less important antigens that blood cells have, and for most transfusions we don't care about them. However, for people who need repeated transfusions (due to a disorder or illness), they have to be careful about those other antigens, because those patients can build up antibodies to them with repeated exposure. Those patients are more difficult to find compatible blood for, and lab grown blood could make it much easier to obtain the required type.
