From your draft IESG Charter:
Network Working Group
40 years ago a group of researchers was funded by DARPA to study
packet-based communications, one part of which was the Network Working
Group. Part of this group has since become the IRTF's End2End Research
Group, and the rest of the functions have devolved on the IAB and the IETF.
The Network Working Group, as such, has not been functional for nearly 20
years.
I personally would like to see us stop attributing documents to them. The
world has long since moved on, and those who don't recognize it date
themselves.
