It ends up being more complicated. You get enough infusions as AB+ and you’ll start picking up strange antibodies that increase your chance for that sense of impending doom
Similarly you could likely receive O+ blood if you were O- without adverse effects, but only once.
I have a relative who has an unfortunate condition that causes internal bleeding. They’ve had enough blood transfusions that their antibodies are completely haywire.
Multiple times, doctors have not listened to their protests, and given them O-. They turn an impressive shade of yellow (among other, more serious, issues).
Last I heard, there were 2 compatible donors known, 1 in a different country. Thankfully, you can store blood longer term. It’s just not cost efficient to do in bulk. They have their own little stockpile of blood at their local hospital (mostly self donated).
Years ago I read somewhere that they discovered a way to remove something from the blood and make it universal, like eliminate blood type all together.
Wonder how that research going?
It’s expensive and blood can only be stored for so long. Easiest to stick with compatible blood types.
There are also loads of other antigens in blood that can cause a reaction. These are just the commonly known ones. So blood should still be cross matched anyway if it isn’t an emergency.
And, quite frankly, we actually are getting somewhat close to producible artificial blood, so there’s just not a whole lot of need for the investment.
And those artificial blood studies have DARPA money behind them.

Blood for the

Now ask plasma…
