It seems that if you do force it to get an error by explicitly

It only refuses to continue if listening on *every* interface
failed.

Is there a
sysctl or socket
option which allows multiple silent port bindings without the second
and later apps getting an error?
Yes. That would be SO_REUSEPORT , and it looks like bind9 does use it:
