Sending a message larger than the max packet size is silently ignored

Recently had to debug this. It should at least warn that it's not possible to send the message, because it's too large to fit in a packet!

I'm a bit confused, isn't this what packet fragmentation is for?

[gafferongames]

Packet fragmentation splits up a packet into fragments. If any of the fragments packets are dropped, the whole large packet is dropped.

Sending a large data block through a reliable channel splits the block up into pieces too, but crucially it resends pieces until they are all received by the other side.
