The idea with this approach is that the current API would remain exactly
the way it is (and each request to the old endpoints would be within a
single transaction, just like today). We just add this "tx" resource to do
transactional operations across multiple requests.

So none of this is decided on, the approach I posted is one direction we're
experimenting in. The reason I can't give you a commitment to some
particular direction is that we're still debating and testing approaches.
It gets complex, because the issue is not just transactions, but thoughts
about throughput and latency as well.
Figuring this out is a high-priority issue, but we are currently spread too
thin to put a full time developer on it. Me and Michael Hunger are working
at it in our spare time, and are making some progress. Hopefully we will be
able to assign a full time dev on it before the end of the year, but there
are absolutely no promises.
I promise though that as soon as we have a workable version to show off, we
will post about it on the list to get feedback on it :)
