Based on irony.

It's the statistics I was given so far, and I find them
already convincing, but if you want harder facts, we could
gently ask Matthias to sit down and count how many octets
those redundant presence stanzas sum up to.

Yes we know what you think of ~50% less stanza packets.
Everyone has his beliefs, you believe in the blessings of compression.
We're not ignoring it, but so far noone found the time to draw up
a protocol scenario with 50 people on the other side of the line.
Version A with 5 presence changes "broadcast" to those 50 people.
Version B with 4 presence changes after one "broadcast" to 50 people.
Then see what compression algorythms make of that.
