Yes, I had this thought as well that adding "apply" doesn't make a lot of sense.
But I thought since the global variable has this name for a long time, there
must have been some reason. I can change the name if the "apply" doesn't hold
any value.

Oh, yeah, you're right. So, if we use `prepare_repo_settings()` in
them, wouldn't
it be better to use getter and setter functions? Otherwise, I'd have to call
`prepare_repo_settings()` everywhere I'm using the setting.
