You might be cherry picking. I think what's happening here is more, this is a new kind of plot. I don't think it's dramatically different from what has come before, but stuff like timeloops and respawns are a really recent concept compared to something like say, reincarnation. So even though it's not actually overrepresented, it feels more represented, because it's recently gone from 0% of all stories to 2% of all stories.
