Personally I favour this solution over #1012 because it's cleaner. But realize that bumping the minimum required version of redis-py can be problematic for any number of reasons.

[georgepsarakis]

Nice work!

[thedrow]

I guess we have to bump the minimum version.
This requires a new minor Kombu release. I'm not too happy about this but we gotta do what we can for the health of the project.

Thanks a lot for the contributions.

[lithammer]

I mean there’s always the #1012 approach, but it adds technical debt to Kombu instead.
