The main reason why people use mod managers is to easily switch between mods without tedious manual installation processes inbetween.
Seeing how that is already accounted for natively (you can just dump all mods in the folder and select which ones should be active, excellently simple and functional system) it probably wouldn't be used very much.
I think I may have misspoke by calling it a "mod manager". The current Starfarer launcher is great for choosing which mods to activate; clean and functional.
And going through the work just for an updater does not seem worth it. All it takes is having a link to the mod-section forum thread in each mod's description that the user checks once every one or two weeks.
This is the "issue" I'm primarily trying to address. Some of the mod postings (and I mean no offence when I say this) don't list either the current mod version or whether it is compatible with the current version of Starfarer.
I would like to call out a mod maker who does an excellent job with his forum post. I have no issue whatsoever determining version and compatibility from just the
topic of his thread. That would be Uomoz. His forum
topic (which he updates on each release) contains all the important information one would like to know.
[0.53.a] Uomoz's Corvus 16.2: POWER BLOCKS (Factions Collection)
I would feel much less compelled to make a mod updater if most, if not all the forum topics had this format.
By no means is Uomoz the only mod maker with this topic format, but his is the first mod I installed, so I have a soft spot for it.
