I mean, that's fine as a personal opinion, but I'm talking from a "success of the setting/brand/IP" perspective, rather than a "lol [insert thing] sux haha" kind of one.
It doesn't make sense to make a massive time-jump when there's absolutely nothing about the sequels and their ending which would require that. If they'd ended with the galaxy either being made perfect and safe for at least decades with President-for-life Rey, or civilization across much of the galaxy being basically destroyed or something, that'd make sense/be needed. As is, very little was locked down by TRoS (one of the few positive aspects of the movie). The returned Palpatine and his hard-to-explain fleet were destroyed, and the First Order scattered or destroyed (like the Empire before them). Almost everything else is up in the air.
