I suppose I will open a new post to signal this weird situation with the list of registered packages.
@stevengj, @bramtayl, I just published on GitHub a set of 3 packages to handle bibliography. Outside of BibTeX, it is currently just a backbone structure for a general bibliography group of packages. I detail this in [Citations in docs - #26 by Azzaare], but basically, there is a package for an internal bibliography type, a set of packages (currently only bibtex) to parse bibliography languages, and one package to wrap all of that and manage import and export of citations.
Now, I would be happy if I can merge those with the bibtex related packages mentioned above 
(I tried to make my packages structure with modularity to ease the process)
