what kind of issues we are still solving with v2, if any

If we drop v2 can we start working on v4 or v3+ there are still some issues
such as returning the generated keys which I think the server can help us
with

As far as dropping code goes, the driver is pretty well written so that
dropping v2 should be a matter of just removing the v2 package. We don't
really have to muck with that code anymore
