I also wonder if some of those almost-successes would've ended up as long runners had there been as much empty space in the magazine as there is now. Like maybe we'd have Oumagadoki zoo, St@rs, Soul Catcher(s), etc anime to look back on if all the big manga didn't push them out.
Soul Catcher(S) would totally survive if it was published now, sales were at the same level of Chainsaw Man:

Sales were good enough for them move the manga to JumpNEXT at the time
