There is no reason to remove that.

do you know somebody who use it? It is dead code. Processing of call
functions should be simpler.

It is not --- it's the recommended solution for emulating computed
columns. The column-as-f(x) direction maybe isn't terribly exciting,
but the function-as-x.col direction definitely is.

"Dead code" means code that can't actually be reached, not code that
does something you don't like. :-)

Yes, see "SQL Functions on Composite Types" (34.4.2 as of CVS HEAD),
down near the end of that subsection.
