Thanks Thomas, yeah, it does clarify, and your points are super valid.
Honestly I guess at the end of the day though, I personally favor approaches that are easiest for the end users, even if that’s more work/a bit cumbersome on the developer side. The developers and implementors have the toolsets to deal with it (though we should do everything we can to make it as smooth as possible, obviously) whereas the end user just has what we give them. Finding a balance there is going to be tough for sure - your point about possibly breaking every AP0 <–> AP1 conversion is well heard! Yikes.
