That opens a whole new can of worms. They have not deprecated a single part of the s3 API ever, in history (okay I'm partially lying, the SOAP API is now officially deprecated in the sense that they won't add new features to it).
They're not going to change it just for the sake of some minor path issues that have a workaround. (Side note: They tend to uses headers rather than paths for API declarations). I have personally been bit by this same issue, but I would never recommend they change pieces of the service to accommodate it. It's handled easily in client code. What they could do is make an obvious "gotchas" section of documentation
AWS has done a tremendous job of getting things right-enough the first time. They have never killed an AWS service. They'd need a much bigger reason to version an API.
