[darcs-users] revision identifiers

[Declan Naughton]

In revision control systems like Mercurial and git, every time the
repository is updated (recorded to in darcs terms) a new revision
identifier is associated with it's new state, so that it can be
referred to for checkouts and such.

In darcs, users MUST MANUALLY use tags, this I consider quite a
downfall. Would it be a bad or a good idea for darcs to checksum the
context and record this with records, and, (being the revision
identifier) printing this out in 'darcs changes', providing for 'darcs
get --rev=xxxxxxxxx' etc?

Or what am I overlooking?

Danke.
