There are a few problems with ICMP source quench:
1) If a sender-TCP actually pays attention to them, an attacker can
substantially reduce TCP performance by forging them (a low-grade DoS
attack).
2) Few if any routers legitimately generate the things (see #3).
3) The Internet community figured out a decade or more ago that the
last thing one wants to do on an overloaded link is to generate even
more traffic.
