Ehh, I used to run a server, and Paper never broke anything that me, or other people wanted to do. You can enable TNT duping and bedrock breaking in configs, and it fixes some unacceptable for public server dupes. Not to mention they have performance reasons too. Features that break under paper tend to break between versions too, because preserving bugs is quite hard. And officially by Mojang there is Bedrock which just makes any complains you have to Paper laughable
