mediasoup is not an application, is a Node.js library. It's yet nother NPM dependency in your Node.js application. No reason to have a DEB package.

Fair point, but there are standard ways to package npm deps in Debian: https://packages.debian.org/buster-backports/npm2deb

For restricted environments limited to things you can get from standard repos this is the only way to get NPM deps.

Yep, I know. However the effort required to make and maintain DEB/RPM packages for different architectures (mediasoup has a C++ component) is huge.
