\public \foo would make \let\foo=\relax in cases were no corresponding \_foo was defined. This would hide typing errors.

Change \_public \foo ; so that we get an error message if there is no \_foo. Users that want the old semantic can explicitly write \let\foo=\relax
Change \_nspublic \foo ; so that we get an error message if there is no \.foo.
Change \_private \foo ; and \_nsprivate \foo ; so that we get an error message if there is no \foo.

Thank you for this idea. Normally, OpTeX macros generates only warnings but this should be an exception because \private etc. are not used in normal document processing.
