I think it came from a place of complete ignorance on the part of the olympics committee of what climbing disciplines are like and how very different speed climbing is. No one takes speed climbing seriously who also takes any other form of climbing seriously. Its a real shame they had to include that in the competition.
I'd heard that because it was a new sport, the IOC would only allocate 1 medal to it. The idea is that it's easier to have the 3 disciplines combined this year and split them into separate medal events in future than it would be to choose 1 discipline this year and try to add additional ones in future.
*when I say "1 medal", obviously I mean 1 medal per gender not 1 total
edit: actually, I've just looked it up and Paris 2024 will have a speed climbing medal and a combined sport/bouldering medal
