Right, for me A' produces the same result. But maybe this is a font-issue.

Forget about superscripting prime .. that's a traditional tex thing as in cm/lm fonts the prime is so big that it has to be (super)scripted to look okay. The prime in unicode is a normal one so that's what we now support, also for the lm fonts. Just compare: \startformula A\prime \hbox spread 1em{\hss or\hss} A^{\prime} \hbox spread 1em{\hss or\hss} A' \stopformula Keep in mind that most users expect ' to be a prime.

Interesting. Thank you for the clarification. I will use A' from now on I guess. Thanks, Paul

What about A_\prime? (that is one of the stated reasons in TeXBook on why \prime in CM is big). Regards, Khaled

Is that used at all? (For that purpose we could have \bigprime or so.)

No idea, I'm not a mathematician. I don't know how \prime is done in MkIV, but with OpenType Math the sizing is handled by the ssty¹ feature, so A^\prime and A_\prime should result in properly sized prime as long as ssty is applied and no other special tricks are involved. \prime on its own would still show a small glyph in most fonts, but this shouldn't be an issue. ¹ ssty maps prime to a bigger glyphs that would be in proper size when scaled down for script size.
