Two things: 1) registering in botobackend.py as requested seems to conflict with the request to follow the newer prefix conventions (where the example of SSH registers each in their own ssh_<backend>.py).  I followed the SSH convention when I renamed it the new backend s3_boto3_backend.py.   2) If i do register the all the s3 backends in a common py file, calling that py file "boto" isn't right for the new one - boto and boto3 are completely separate. If that's the registration convention you want to follow, I'd suggest "s3backend.py", which would collect the two older "boto" backends, and the newer "boto3" backend. But, I don't see the point of breaking the encapsulation of "everything in the new backend is in the new backend file, including registration", which is what ssh and most non-prefixed backends do.

I think you are looking at an old diff. I updated that when I switched from --s3-use-boto3 to boto3+s3.   Did I need to do more than push my change to my branch to update the merge request? (First project that I've used bzr in...)
