I can justify in my mind that Adobe on the back end would want to keep a log of the plugins someone may have at least tried to better understand what tools would meet that persons needs. But that can surely be a log file stored somewhere out of sight on the Adobe servers.
As for the average dedicated consumer of Adobe CC products, I think I speak for many of us in saying that we are a bit... obsessive to borderline demented about meticulously curating our assets and resoures.
I installed a plugin to connect to cloud resources, immediately found out it didn't meet my needs, found a better plugin, uninstalled 15 minutes later. 4 years now I see that plugin everytime I go in to do an update.
Installed a plugin for Punch and Roll in Audition, a month later Audition updated and had Punch and Roll natively. Installed a notepad plugin, realized it wasn't even a notes panel within the software, just a windows notepad luancher. 3 years later I still have cluttering up my "manage plugins" window.
It's maddening. It makes me hesitant to try other plugins that I may not like and be forever stuck with sitting there in my panel gathering dust. I've seen multiple complaints from other users that they are unable to get rid of plugins that are no longer even compatible with new versions of the software.
Us creators are a neurotic people. This is neglicence bordering on cruelty.
Ok... maybe that last statement is a bit much lol. But it seems likea no brainer to me. The "correct answer" to all that I've seen asking about this issue is pretty much a non-answer of "that's how it works. case closed." As if to say, "It's not broken or anything. It's stupid and frustrating on purpose! glad we could help resolve this for you."
If I can see the option to remove plugins from our Manage Plugins menu by years end, I will feel like I made a notable positive impact on this community. To me, it seems like an oversight. I don't even understand the logic of it being necessary.
