This is a most excellent place for technology news and articles.
Freezing an app in an non-root fashion doesn't do anything special. It's moved to a different location and is effectively "removed" from a runnable state. The OS shows it as disabled/removed, but the files are still there. Newer versions of android (14+) will recognize applications it thinks are necessary (like this one, from Google) are moved/disabled and will pull a new apk during the upgrade process. It effectively re-installs the app.
By upgrade, do you mean OS upgrade?
