Hm, does it matter?  I think those wrappers send the output to /dev/null
anyway.

The debian ones don't, because they consider it useful information to the user. I'd say that it is, especially in the case of pg_upgrade. (Less so about initdb, but still a bit -- especially when creating secondary clusters) 
The redhat ones I believe sent it to a logfile, not to /dev/null. Meaning it's not in your face, but it still contains incorrect instructions.
