24gb is as big as the M3 can be built given the available LPDDR stacks. The bigger crime is that the 15" can't be configured with the M3 Pro... particularly given the less-ambitious spec compared to M1/M2 Pro. Things like not supporting a second external display make the 15" MBA a non-starter as an 'ultrabook' even with 24GB configurations. With the M3 Pro, since you get a 192b memory bus, you'd have options up to 36GB as well as dual external display, which is at least adequate for the class of product.
