Really?  So unlimmited numbers of packets with identical C2S, S2S
and master key, differing only int ehnonce is not a problem?

Pretty much every crypto algorithm I know of has a recommended
maximum number of uses.  Allowing these two to be used unlimited times
is violating absic crypto principles goint back to well before how
Enigma, and other ciphers, were broken.

Yeah, bad.
