Why do they think this is better than 5xx?

Not that I know of.
The closest thing I can think of is a retry rule for the domain that matches
timeout & refused with a reasonable retry values followed by a retry rule
for the same domain matching everything else with a cutoff time of zero.

It's domain- not host-based, but I think you might look at hold_domains:

If I've misunderstood you, maybe queue_smtp_domains or queue_domains would
work better:
