Deprecated features are still part of the language.  A conforming
compiler can't reject a feature solely based on the fact the the
feature is deprecated.  More importantly (i.e. the subject that fired
up this discussion), existing codes written in conformance to an
existing ISO standard won't just vanish because the next standard
*may* deprecate some supported features.

You can also conform modulo bugs in the compiler.  One just needs to
define what counts as bugs.
