I will briefly reply on the packages created by the BgLUG group. Outside the LibreSchool project, they are much more than crippled: they are quite tightly coupled with software/technologies which are implemented in the project but usually not needed in all environments, so it may not have sense to them “generally available”.
A second reason is that for some solution we found we never bothered to package the needed stuff (and we should have done that, anyways).
Still, I do think this is a good idea: it is a single point where people can check if and how other stuff is implemented outside default repositories. I would recommend to link in that page the sources (github as you did, for example) and if available the created packages (ours are here).
