There was: Secrets* was both a website were people aggregated a small database of these options and a MacOS preference pane which displayed these:

(* by the makers of Quicksilver!)
Sadly the project stopped updating in 2012 and the website, repository and forks seem all long gone.
(Should anyone resurrect this great app, one improvement should be versioning of secrets recipes. AFAIR Secrets.prefPane displayed options long after they stopped applicable for later Mac OS versions.)
Why would an app like this require a subscription and not a one off payment.
I think many small developers are taking cue from large enterprises on how to price products without thinking it through. There was another similar discussion about a YC macOS notification widget company the other day.
Just slapping a subscription to a regular desktop application doesn't make sense.
Also, bundling is not a justification for a subscription, especially if one only cares about a single application. This is similar to the music albums which have already undergone unbundling and no one wants to see a bundling where there is no benefit to the consumer.
It’s probably not exhaustive, but quite convenient.
However, like other people, I'm not sure that I agree with this particular set of changes. Is there a project somewhere that packages these options into a GUI? I know a bunch of folks who use OS X who might want to change these things, but they're not programmers and they don't even know shell scripts exist.
