Do you have a suggestion for how we’d mitigate this issue? It seems to me that all we can do is:
- Note the issue, so that if people hit it they have a place to find out what happened and what to do.
- Prioritise implementing PEP 685 in consumers before producers.
If you want to add a clarifying note covering these two points in the “backward compatibility” section of the PEP, I’d be fine with that. (It’s not technically backward compatibility, but that feels like the best section). If we’d had a “Transition Plan” section as I proposed in this post, that would have been a better place for it. I guess we could add that section if you want to.
