If you wish to believe that, believe that, but it is only wishful
thinking.

ULA is normally used in parallel with public addressing if it is
used. IPv6 was designed to be deployed with multiple address and
prefixes per interface. When ULA is deployed you have ULA <-> ULA,
non-ULA <-> non-ULA. Non-privacy addresses for server functionality,
privacy addresses for client functionality.
