To do that we'd have to use separate code for I/O and casting. As
an example, this current behavior is unquestionably contrary to the
spec text I cited:
regression=# select ' 42'::text::int;
int4

(1 row)
regression=# select ' 42 '::text::int;
ERROR: invalid input syntax for integer: " 42 "
regression=#
