Restrict macOS from automatically enabling "Keep in Dock" after rearranging Dock icon I like to have many programs running and move around things as needed, but I hate keeping anything permanently in the Dock. As of now, I have to manually uncheck Keep in Dock every time I move an app icon and it's really annoying. I don't want to do that anymore. How do I disable that feature?

This has nothing to with "Most recent apps" as that's already turned off.

Also, this question has been asked before, but everything I've found is 3+ years old and no one has an actual solution. I'm really, really hoping that in the few years since then Apple added some basic customization.
This is the expected behaviour and has remained the same since the days of Mac OS X 10.10. There is no way to prevent it from happening.

It still stands true, as of this writing, with the current latest version being macOS Mojave 10.14.5.
