I don't see a contradiction. There is clean agreement, so ERROR level
should to show the context. NOTICE and WARNINGs doesn't need it - and there
is a backward compatibility and usability reasons don't do it.

I am not to against to any special option to RAISE statement. Have you some
idea?

What about a enhancing a USING clause?

example:

RAISE NOTICE USING message = '', with_context = true
RAISE EXCEPTION USING message = '', with_context = false
