And to clarify a few things for some people DAISHINKAN does not belong to the 7(seventh universe), and he was cited as someone that Goku needs to go through, the statement that Broly, Bills, Whis, Daishinkan, are superior to GOKU is largely, it is general and not limited to the seventh universe only, otherwise the daishinkan would not be mentioned.
So, if you deep down think that JIREN wasn't mentioned because it's part of another universe, you're wrong. Native Japanese confirmed that when UCHIDA (who is more relevant than you) mentioned Broly, Toyo nodded and did not refute or disagree with UCHIDA's speech to his editor who is helping him.
