not at that gigantic size...but I would love an inter-user package repo independent of The Solus Team, of stuff people have modified, compiled, and tweaked that can only be it/rm byeopkg.
that would take a lot of trust and policing. in the end it may end up being more trouble than it's worth. but maybe not.
The AUR gets away with this because Arch users (unpaid) have stepped up to do the policing/re-readings code.
[I do run AUR packages on Arch but I hate to say it: flatpaks much more stable. AUR stuff mostly behaves weird for me: zoom, epsonscan2, scribus, ungoogled chromium, etc and I have to uninstall after it's floundered and get the flatpak version. Not everything at AUR failed me...but enough has].
