They stop at one point with the filler episodes, but instead pad out the length of the actual story, which is arguably worse since you could just skip the filler before, but that isn't possible anymore.

There is a page called One Pace, where they essentially cut out everything unnecessary, I heard it is good, but haven't tried it myself yet.

Maybe once the manga and show end, they can do something like Dragonball Z Kai where they release a new version of the anime with all the filler cut out and tighter pacing. It would be a good way to bring in people who are curious about the series, but intimidated by how huge it is.
