<p>Ignoring the question of whether it's useful or not I can't say I'm especially keen on adding it as builtin metadata, at least under that name. Frank I see it as confusing to return something purporting to be a changeset count that is actually a snapshot of the historical count at the time that changeset was created.</p>
<p>What it actually amounts to is a per-user sequence number for the changeset and if we were going to add it I would to name it along those lines so that it's purpose/meaning was clearer.</p>
