Uhm, not sure.  I'm not really used to having DO available so I didn't

I dunno.  They have been proposed and shot down in the past.  Apparently
people don't want psql to become too powerful.  ("But that would make
psql turing complete! Soon you're going to want to have \while on it!").
I think pgbench is supposed to be designed to handle data in bulk which
is why I started using it for this in the first place.
