Why did you make this change, especially without notifying the original editor (me)?  `surface=compacted` is the correct tag for these roads. While `compacted=*` is not a currently accepted tag, it does not do any damage to add a detail to the accepted tag on these types of roads.

Regardless, if I (or someone else) is incorrectly tagging something, it is polite to alert that person rather than just mechanically change things to your preference.
