No, it isn't. What you're proposing is to let opr_sanity think that
text and anyelement are interchangeable to C functions, which is so
far from reality as to be ludicrous. That would be seriously damaging
to its ability to detect errors.
But more to the point, your analogy to quote_literal is faulty anyway.
If you looked at that, what you'd find is that only quote_literal(text)
is a C function. The other one is a SQL wrapper around a coercion to
text followed by the C function. I rather imagine that the definition
as you have it would crash on, say, value_to_json(42).
