How does this relate to T19577? – What does it mean to do this as part of Thumbor release?

The Thumbor release doesn't depend on this. We could do it now, even, we'd just have to tweak the thumbnail url scheme slightly through the whole stack.

Regarding T19577, timestamp-based versioning tends to be fragile in my experience. Particularly in a clustered environment where separate DCs could race on generating the same thing.

We should revisit this later. I think that a new service replacing and subsequent changes to the url scheme would be more appropriate.
