Don’t really see the point of new syntax here - both things you wrote are
already effectively syntactically valid if a user-defined function exists;
and it’s a cleaner interface.  Plus, the serialized form of a composite
doesn’t include field names so giving those names special treatment
elsewhere feels excessive.

Expanding cast with custom features seems particularly undesirable.
