yeah he did say he was glad that he did not die of old age or disease but my point was targeted to some ppl who disregard his optimistic ambitions and reduce him down to being just happy to meet geto again bringing him some sort of peace after his "sufferings". trust me i've seen them wording it like to show gojo wanted to be at rest as if he was depressed. he can be happy to meet his friends again and have unfulfilled wishes too. gojo's significance to his students were his ideologies so he cant be put to rest unless they fulfil his wishes is what i think.
