Yes and no. It's certainly true of most packages but the smaller the package, the more likely it is that the distro package maintainer will be [a/the] maintainer of the original project, even with Debian.

The same is true of Homebrew, etc. - most of the package maintainers aren't the original project maintainers, which is ultimately why MacPorts support is so comprehensive despite not having anywhere near the same user capture as Homebrew. But the places you see frustrating gaps will always be at the edges, where it may be the original project creator creating a Homebrew package & no-one packaging it for anything else.
