I'm not a developer, but I am quite interested in seeing this happen. I was able to build a test package on a stretch VM by: - downloading the 1.3 tarball from upstream - grabbing the debian directory out of git (https://salsa.debian.org/ron/opus.git) - updating debian/changelog with a test entry for the upstream version (I called it 1.3-1) - running dpkg-buildpackage -b
So unless I'm missing something, it should be fairly straightforward to sync salsa up with upstream and push a new package out.
