Oh no guys does this mean what I think it means

Now that we know that if you build on top of the school the ghosts will be trapped forever, does this mean the rest of the point of the show or an ending point of the show is going to be getting all of our favorite ghosties to move on? I feel like they’re all becoming so fulfilled in their existences and growing and but also happy for the first time in a long time and I don’t want it to end for them. I know they are technically dead, but they’ve sort of been given second chances at life by being in this school, and it’s basically akin to dying to cross through those doors. They have no idea if there is anything that comes next.
