If someone wants portable code, they can use a development tool which
wraps ALL identifiers in quotes, every time. That's what we do. The
important thing is that, to the extent practicable, standard SQL code
is accepted and behaves in compliance with the standard. I don't see
that it does anything to compromise that if you support additional,
non-standard syntax for extensions.
