I've seen more than one instance where a critical system has
to add an interface on the fly to either (a) replace a failing interface
while maintaining traffic on all the other interfaces or (b)
add an interface when all installed ports are busy.

Saying "you shouldn't do that" or "why would you want to
do that" shows lack of real-world experience.

That said, I agree that the Linux solution is bad.
OpenBSD reports hardware during boot and new hardware
with kernel messages. Using that information to configure
the appropriate daemons and utilities is the right solution.
