I look at clean installs as a last resort. I keep a pretty clean image just in case, but keeping it up to date with things installed on other drives is tedious. Honestly clean installs as a preventative measure is a bit overkill. Most people have no issue with updates, some do. A clean install will prevent issues. But you are doing the work before you ever encounter an issue. Same with delaying updates, I have an image to revert to which takes about 5 minutes, so I don't delay updates.
