But do they have decided because they thought about it, or followed by

It's not obvious to users trying to look for what version the checkout
was. Maybe noting down in README.source how the specific dated checkout
was produced would be helpful in that respect.

Erm, so you rather like to push off the traceability requirements of
where and how the upstream version was received to an "interpretation"
of a tool rather to use proper informations that you actually have at
your hands? Nice call, really userfriendly. :/

to get the same upstream source that you package won't fail with that

The only thing here is that a date is ambigious with most VCSes when
not also adding time (and timezone) informations to it, so it doesn't
gain you too much.
