I assume that tracert using ICMP is not that much an WinSock limitation but limitation of the underlying NT security architecture without suid binaries, which was worked around with ICMP-only non-privileged “raw sockets”. But that is mostly an educated guess.

This is a limitation that dates back to NT 3.1 where SOCK_RAW was callable by standard User accounts. Only starting with Windows 2000 [0] does creating a RAW socket require local administrator rights.
