The issue I see with only using the date is that Git dates are not unique, in order, or even meaningful in a clear way.
Commit dates don't have a consistent meaning: are they the time of first revision of a commit? Final revision of a commit? Time of signing? Pushing? They are often useful to estimate a timeline, but it's common for a Git "timeline" to jump back and forth by months or a year due to long-running development branches being merged in, or due to a "commit and then polish by rebasing" workflow.
Using the revision ID (of sufficient length) gives an unambiguous reference to the upstream source of a package and its artifacts in the store. How would you describe a package version to upstream when reporting a bug, except by revision ID? You can't tell them a timestamp and expect them to know which code a buggy package is based on.
We could certainly add a timestamp to our version strings for VCS-based packages, but we should keep the revision ID too.
