What do the "Debian Package Maintainers" do? First of all they take someone else's software package. Then they move the directory and file structure around into different places according to some arbitrary notions. Of course everything was better before they moved it, and everything worked without the changes, which were completely unnecessary.
Then they make a "package" of it. Then they stick some extra notices on the package telling you to report bugs to them, and they will report the bugs back to the people who made the software. Of course it would be easier if you just reported the bugs to the author of the software, not the Debian person, who doesn't really understand the software anyway, and who then has to run around reporting the bug "upstream" where it should have been reported in the first place.
Also they make their own little scripts to do things like installing software. Many of these scripts are not carefully written or robust.
What these people do seems just "busy work": pointless meddling with software packages which didn't need any adjustments. In the worst cases bugs are introduced by badly-written configuration files introduced by the Debian maintainers.
Plus the documentation of Debian is not only extremely bad, but it hasn't improved in ten years. In fact it seems to get worse rather than better.
