IIRC there were objections the last time it was seriously proposed,
basically of the form "but that will break my application which relies
on writing so-and-so without a cast". We did get as far as removing all
the implicit cross-category coercions except these casts to text:
bigint | text
smallint | text
integer | text
real | text
double precision | text
numeric | text
oid | text
date | text
time without time zone | text
time with time zone | text
timestamp without time zone | text
timestamp with time zone | text
interval | text
but these seem to have a constituency :-(
