                                                               ^^^^^^

This section of the document says _nothing_ about sending messages.   It 
specifies what a client must be prepared to receive.   This is not an 
interpretation - it's what the text says.   It says that a DHCP client must 
be able to handle _at least_ a 576-byte packet on input.   This means that 
a DHCP server cannot assume that any client can accept a packet larger than 
576 bytes unless the client says it can by sending the maximum message size 
option.
