I've never really considered these to be more than tagging for dataset 
maintainers, I didn't really think that any data consumers would want to 
use these. I would not put these under ref=* as they aren't really 
references that end users would see.

The two options would be:
1. the ref: namespace or
2. ref:AU: namespace which is similar to what the FR community seems to use:

Any opinions?

If this is how people would like to tag these types of ids I would also 
have to go back and modify all of the others I have created over the years.

The majority view at the time that we discussed this was to add a source 
tag. I understand that the source tag does have a decay function as to 
it's usefulness but it's still better than changeset tagging, which 
become useless the moment you upload the data. Maybe if Overpass could 
search for something based on the changeset tags of the last modifying 
changeset they would be useful, but till that tag I prefer to have them 
in-channel.

If the general view is now that adding a source tag is not worthwhile 
then we can leave them out.

I agree with you 100%. The reason the current workflow has us deleting 
the outer ways before uploading is because this is what you wanted:

I'm happy to upload valid boundaries which is what I suggested:
