It's a form of one, agreed, although let's be honest - someone reading the transparent proxy use case in the commit message will not think of a complex AP scenario, but rather of a locally configured transparent proxy with IPtables or sockets or such.
Transparent proxy could be implemented using eBPF + XDP and those don'tneed sockets. However, in that case we do need to block those specific ports
to avoid messing with unrelated traffic.
