> Now, who sees schemas as an urgent need and why?

I do. Regardless of what rest features of the above are implemented, the
two-level namespaces for database objects is of high priority, at leat
in Java. Too many tools on the market simply rely on schemas being there
and Firebird is thus not supported (they very often generate "foo"."bar"
names to access the objects). One of the most prominent examples is
Eclipse - we still do not have normal support for Firebird there.
