AFAIK speed climbing used to be a discipline that top climbers from lead and bouldering looked down on, because (for them) climbing is all about solving new and difficult problems and not just speed on a standardized. Overall, it is a bit weird to mash all these disciplines together and the results are a bit funny, with most athletes having one discipline where they placed much worse/better than in others. With all the different running, cycling and swimming events, surely other sports can have some differentiation between different disciplines as well (at least speed climbing will be a separate event by 2024, I understand).
