We tried to get Dragonfly Reverb into the upcoming Debian, but we missed a deadline, so I think the next chance is in 2021. KXStudio's packages are updated so rapidly that it's probably better to keep them separate rather than try to work with Debian's glacially slow releases.
I don't know why FalkTX opted to have a separate repo, but I believe it is some reason along these lines.
Getting packages into Debian repos is not very easy: there is a very specific process, requirements, guidelines and deadlines to be met.
On top of that, there is not just one repo. Audio software typically gets updated very often, while Debian Stable repo needs extensive review to push new versions. It might be more of a complication to have backports or packages into the non stable repos for both maintainers and users with respect having a separate repo.
I believe that, most likely, having the separate repo is the easiest and best choice for both maintainers and users.
