>>> That might be useful for those depending on it, and presumably there is a \stackscripts, too. Just comes to my mind:
>>> Though probably non-standard in typesetting, one might make a slight typographic difference between π₯Β²β and π₯βΒ² by letting the sub- or superscripts that come later partially, but not fully, to the position of the one that comes before. For example, π₯βΒ² might mean the square of π₯β, and π₯Β²β the component 0 of π₯Β², not necessarily the same. Traditionally, such things are left for the reader to interpret.

But then what would happen, even perhaps not that common, if one would need to have it stacked somewhere else in the formula. So in my mind, this would be just top level \unstackscripts β¦ \stackscripts β¦ \unstackscripts.

well, playwith what we have now and we can always extend it
