IMHO, as a casual-modder? Yes. Things were AMAZING circa 2016-2019....now everything is just cars ( a lot of them amazing for sure), ped-accessories and MAYBE a neat looking script that i will get bored of in 24 hours.
Since that time, all my favorite mods are dead it seems. I used to combine NVR, WOV, Visual V, and Real Rage v and as a result i would have a lively world that was fun to sandbox in AND looked hella cool with minimal effort. Hell, i LOVED the vanillaworks mods...but now it seems like mod authors in general haven't updated in months/years and are either gone or moved their files over to patreon. I would love to get into HKH's mods, but i always wind up with a game-breaking bug of some sort. I don't have a whole lot of time for manually editing things in OIV or troubleshooting, so it makes things unappealing when i have to screw around with mod configurations, or create new RPF's for the mod folder and then manually edit them one by one.
I wish i had useful suggestions, but i don't. It seems like a lot of people are doing this just so they can get hired by a studio. How many mod authors have dreamed of releasing a mod in order to get noticed by Valve, Bethesda, Rockstar, etc. A lot, i would imagine. Something similar to the current state-of-decline happened with FO4 when the nexusmods controversies happened and thousands of mod authors had a collective hissy-fit over not being able to delete mods from mod-packs. People can't see past their egos, let alone be bothered to create a user friendly experience for both casuals like myself and the advanced users such as OP....and sometimes, people just simply get bored and move on, which i suppose i have a way easier time understanding and forgiving since there is no point in doing something that both bores you and doesn't pay.
Now, am i owed quality mods or entitled to mod authors labor? No, but that was never really the point of modding IMO. It was always something that people did out of genuine passion for the art or because they just wanted to expand on a game they genuinely loved.
Maybe there are good mods being released, and i am just being lazy as i enter my mid 30's...but mod quality and diversity-of-selection seems to have atrophied and/or declined. The community at large seems to have been atomized by discord and patreon.
