This extension is only mildly useful. The UTM parameters are generally pretty coarse-grained. They don't add information that comes close to individually identifying users. Especially compared to the rest of what Google Analytics tracks by default, the additional data from UTM parameters is very small.

Your privacy is much more impacted by the GCLID and DCLID query parameters, which are added by AdWords and DoubleClick campaigns respectively. This are auto-generated by their respective tools and are much more granular.

IIRC GCLID and DCLID parameters can't be queried except by Google Analytics.

utm parameters also appear in your web logs, and can totally be used to identify individual users.
