It's trivial to grep all system service files for the relevant lines to see if they override the default. It is also easy to override that override to set it to whatever you like of so desired.
Then watch for changes. Or remember to do this on more than one system. Or work with a team of people all credentialed to make work related system level changes to the fleet.
Yes, there are ways to deal with anything, but less is more, this is unix afterall. I can't love having a bunch of options, in several places, that may override each other, most of which I would never use for any practical reason anyways.
Reminds me of the type of systems I abandoned in favor of linux.
