As any Sims 4 players with a tonne of CC can attest to, merging them into as few package files as possible can do a wonder for loading times, but doing so requires manual work in both tracking mod updates and rebuilding the package files whenever one updates. I think that if Curseforge added the ability to create groups of CC the user has downloaded and have them merged into a single package upon installion to the game it'd be a big net gain for the Sims 4 community as it'd largely automate the processes of keeping track of which mod updated and which package file you need to remake as a result.
The only pitfall is that some mods (Mostly script mods) aren't able to be merged without introducing new bugs, problems or straight-out breaking everything unless the user does some extra work, although I think this could be resolved by allowing the mod authors to specify if their mods mergable or not when uploading.
When there's a new update for a mod, you update it through the app and it replaces the old one. You don't need to manually update. If you meant something different/more, please explain :]
