Almost all of the changes flip an official setting. Those stay around for a long time and get a proper deprecation notice when they go away, so you won't be surprised. Replacing systemd-minimal with the full version may potentially cause some edge case issues, but it's the same package with more features enabled, so I wouldn't really expect any. Nothing will break when the package gets updated as long as you keep to your specific release - backported changes are backwards compatible.
