Is 'your' queue better than everyone else's? Why not do a 4xx tmpfail

Why bother even having a backup MX if all it will do is return a 4xx? Why
not let the sending server just fail to connect you your server and it
will retry just as long before failing.
low priority MX's server two purposes:
1) high availability
2) load distribution
Your complaint is that tempfailing negates #1. It does not, however,
negate #2.
Further, if your backup MX's are smart, instead of stupid, keeping some
form of state about valid destination addresses, then #1 is not negated.
Personally, I'm not afraid of tempfailing. Temporary delivery problems
are what 4xx codes are for.
