I think this is a move in a useful direction.
The build date was somewhat meaningless.
You typically look at the version info to know: Does this still include bug X? Does this already include feature Y?
A release number "1.2.3" was useful when releases happened once a year.
But as software is updated more frequently, and you can't wait for everybody to agree on the next release number to assign, you might be running with "1.2.4.SNAPSHOT".
The build ref, e.g. git commit code, would in that case tell you exactly what you have .. except it's a little hard to parse.
Perfect would be, I think, showing both the build rev and the commit date.
From the commit date, a human can quickly see if the snapshot is before or after some key date when bug X got fixed.
If it happens to be the same day, then you dig down into the git commit code.

Thanks,
Kay
