The services:
bounce unix - - n - 0 bounce
defer unix - - n - 0 bounce
trace unix - - n - 0 bounce
are internal Postfix services, and are NOT delivery agents. They
are needed for the proper operation of Postfix, and you're not
expected to (you're expect not to) change these.

On the other hand, "discard" is a delivery agent, and so cannot
replace the "bounce" service or vice versa. The Postfix delivery
agents are:
smtp unix - - n - - smtp
relay unix - - n - - smtp
# -o smtp_helo_timeout=5 -o smtp_connect_timeout=5
error unix - - n - - error
retry unix - - n - - error
discard unix - - n - - discard
local unix - n n - - local
virtual unix - n n - - virtual
lmtp unix - - n - - lmtp
somepipe unix - n n - - pipe
flags=DRhu user=luser argv=/usr/bin/somepipe -- ${recipient}
Handled via local(8), virtual(8), smtp(8), lmtp(8), pipe(8), error(8)
and discard(8).
