Also when additional locally generated ULA prefixes are present after a network join. I recognize this view may be in a vocal minority, and I can live with a more persistent locally-generated ULA prefix so long as there is a standard scheme for dealing with prefix accumulation after network joins.

Minority versus majority isn't the issue.

The reason I object to this is that you have control over the lifetime of your ULA, but not over the lifetime of your GUA.   Do we really want a forced flash renumbering from the ISP to break connections on the local network?
