Are you sure the change is worth it ? It's true that it's more consistent, but still, 99% of the time, the user doesn't want to see "NULL" all over the map. The coalesce expression isn't easy to find out for beginners neither.
For me it's a -1 unless we have an easy way to hide null values (maybe a checkbox somewhere in the labeling settings to toggle display of null values, but this is a bit a duplicate of the data defined "show label", or maybe having coalesce as the expression by default, but this feels a bit wrong too). Also I'm not sure it's correct to display the NULL string on the map, as it's an user-defined option. This means that a same project file could be displayed differently on different setups...
