an IoT device that can be crashed by server just sending valid and expected
messages is horribly broken

if it can't handle such messages, I seriously doubt it would handle 
messages
from an actual attacker (which, need I remind, MUST be handled correctly 
and
result in orderly connection shutdown, one that hopefully includes Alert
messages)
