I do think there is currently a bit of hole in the lineup, but I don't think it is that big. While Apple very well may scale up the 24" iMac to 27" with an M? or M? Pro chip, I think their answer is a Mac mini/Studio + Display.
A Mac Studio + Display even with some spec upgrades gets you under the cost of the iMac Pro, so that market should be met from both a power and cost perspective. An M2 or M2 Pro Mac mini (once 32GB RAM is an option) + Display would more or less cover the 27" iMac segment from a power perspective and somewhat cost. There is definite a few hundred more required, but I'm not sure Apple sees this market as big enough to devote resources to.
Unless they really are planning a massive "Pro" upgrade, I can't see the logic of not scaling up the 24" iMac unless they genuinely have no intention of replacing that product or the supply chain issues are that constraining.
