Perhaps not.

It doesn't seem very outlandish to me: the alternative would be to repeat
all of a query that might span dozens of lines, in order to change one or
two lines. That's not very readable or maintainable.
I'm prepared to believe that extremely long queries aren't ever going
to be common in pgbench scripts, so that there's not much need to support
the equivalent behavior in pgbench. So maybe it's fine.
