There were a number of people complaining about the slowness of
RightAWS. That, and the fact that there was no way to do anything
without making at least one http request to get the bucket. I could
work around it for building URLs, but for uploading it meant I had to
make at least two http requests. AWS::S3 doesn't have that limitation.
And a few people were having issues with connections, which
RightHTTPConnection was supposed t prevent. It turned out that there
were fewer and fewer reasons to keep using it.
