Am I missing something?

That's actually a very fast path: connection establishment both for
listened and connection sockets (tcp_init_congestion_control() is called
for TCP_SYN_RECV state too), so you forces every socket allocation (if
appropriate congestion contttrol requires that) to be doubled.

This actually may be not a big problem, since we allocate and free
objects all the time, but still it is additional overhead which can be
avoided. Did you run some perfromance analysis to check if influence is
small or not visible at all?
