I'm a bit confused why there was no reply to this. I mean, it wasn't sent on
1st April, the patch still can be applied on top of the master branch and looks
like it even works.
I assume the main concern her is that it's implemented in a rather not
extensible way. Also, if I understand correctly, it compresses the data stream
in both direction server <-> client, not sure if there is any value in
compressing what a client sends to a server. But still I'm wondering why it
didn't start at least a discussion about how it can be implemented. Do I miss
