I've shot 8+ majors a year for the last 4 years. A5 for the last 5 years, 2022 CO nats, 2021 SS nats, 2018 L10 nats and the last FLOP Shannon Smith put on. I haven't seen a match yet that I walked away as a C/B class shooter saying it was too hard. Sure there have been some stages where I was like how in the heck am I gonna do this. But to me that's fun. Double half IPSC targets on swingers 30 yards away was spicy but fun. This year at A5 there was a stage I know for a fact very high level GM shooters were complaining it was too hard. To me it wasn't. One side was upper half of USPSA target with no shoots in between and other side was 4 full uspsa targets with different parts as hard cover. Had to shoot one side of stage strong hand, then move to other box and shoot either strong or week hand. The hard cover targets were pretty far out but not impossible. I think they had this stage at race gun nats as a fixed time stage. It was super fun and you could shoot fast (as I did) and risk a few Mike's or slow down on SH/WH and make sure you got the hits.
TLDR: I haven't seen the so called too hard match yet. I have seen plenty of the hoser matches both locals and majors and if it becomes common I stop going.
