Well, I think the current state is just provisional.
Last summer in Prague I talked a lot about that with splwnd. The plan must be of course to have a plattform for the mods, where a modowner can upload and others can download it. Preferably integrated into Factorio and automatically downloading all dependencies. A modpack would then be just a mod.json-file, which defines all dependencies and the rest is autodownloaded.
Anywhere there the future lays. It's definitely not in the forum.
I would prefer - as a intermediate provisional state - to look into the wiki:
https://forums.factorio.com/wiki/index.php?title=Mods
More and more modders begin to make entries here. I think that is the better way, cause you can sort the wiki-generated tables by version etc.
It's a mass of work to keep that uptodate, so the next logical step is, that all modders use parseable descriptions of their mod-articles. (Hint: make your mod-head-articles, my mod-owners! that will help a lot!
)
To make it short:
1. We should use the wiki, to bring the most mods into a table-form.
2. The list should be generated by an automated script, which reads the forum-head-articles for each mod.
3. The end-target is then to use this parser to create a database, which can be used to pre-fill the first version of an integrated modding plattform for Factorio.
Or in other word: I don't see the benefit to fix a broken state. A forum is not thought for that job, it would need much manual intervention to make and keep that functional. Or to say it differently: Instead of repairing a provisional solution I prefer a better plan, which will bring us in the end a much better gameplay.
