If it works for you then use it, however if you want the latest packages you’ll have to NOT use the LTS releases in which case be prepared to do a FULL REINSTALL every time a new version comes out.
This is just wrong. You can update the LTS release to the next non-LTS release. You only have to unchecked “LTS only”. You can also wait for the next LTS release.
You never need a full install. I haven’t done such a thing for a decade.
