Well, that's what I mean though - they only included the original characters as nostalgia bait, and then wrote them out of the plot as quickly as they felt they could get away with. They certainly had no plans to continue writing stories with the original characters, and look, they disposed of Ackbar off-screen. It was literally just for trailer scenes so they could draw people into the theaters.
Of course, with the absolutely pointless sideplot they sent Finn on in The Last Jedi, and the batshit discombobulated plot of Rise of Skywalker, it's not clear that Disney had any plans for writing stories with their new characters either.
