This seems like a change for the better. Having the /system partition writable is a lot of unnecessary attack surface. > Rest in peace Titanium Backup, ROM Toolbox, Root Explorer, SD Maid, Lucky Patcher, etc. etc. I'm not sure what the author is trying to say here, because I don't think any of these apps write to /system.
