I know how you feel.. I'd like to delete those apps as well as News. I don't think it would hurt anything to put them in a folder in the back of Launcher or the Applications tab of Finder. Might help you a bit.not absolutely needed due to space or anything no, it's just my fetish for having as clean a system as possible that's kicking in I guess..I´ll ignore it, thanks
I ran nothing but GNU/Linux and BSD for almost 20 years and what you mentioned seems like a lot of work for very little gain. I realize it can be done, but my mind says "why bother?".. especially since there is no guarantee that the work won't cause issues elsewhere.Anything in /System/Applications is under System Integrity Protection (SIP). Additionally, if you have an SSD, it's in APFS format. The System level stuff is in a read-only partition. From what I've seen on the interwebs, at minimum, need to disable SIP, and might have to stay in Recovery Mode and mount the read-only partition as read/write. Command line to delete things.
#!/bin/bash
# IMPORTANT: You will need to disable SIP aka Rootless in order to fully execute this script, you can reenable it after.
