I've apparently come across words with 3k unique kanji and I am still missing 30 常用漢字 and 200 marked jlpt1, I think those might be mostly 人名用漢字 though and I'm not sure how useful that would be during a test which i'm not even that interested in taking.
I might just have to manually look for some vocab if I'm going to fill that gap one day.
I kinda feel like 常用漢字 deserves to be expanded a bit since some of the 表外漢字 are extremely common, but I don't know how Japanese people feel about it and it probably doesn't really matter when they learn how to read them just by reading entertainment and chatting together anyways.
