No, I'm interested in this too.
If I wanted to know the primitive which was valid at the certain point in
time, currently I would have to query the whole history with
find out the version from the timestamps in the history and then retrieve
the primitive with this version using
The API could be extended with
which would reply all primitive versions in the specified range.
Is there any reason why we can query changesets in ceratain timerange, but
not primitive versions?

Ok, next question: is there a way to fetch full history for more than
one node at a time? I'd prefer to not have to either (a) download and
parse the full planet or (b) make tons of node/history queries to the
main API server.
Planet won't help as it doesn't have history, and if you do try scraping the
history from the api you will find yourself blocked
as soon as I notice...
When someone changes a way by moving/deleting/adding nodes there's no way to
see what it looked like beforehand?
That's disappointing. Am I the only one that cares about this? With
permission I'd be happy to try and write something for the openstreetmap.org
site to make this feasible and not kill the API frontend servers.
