To be clear, again... Winsock 2.2 provides several mandatory features
which are integrated into the driver code;

1. recycling sockets (through TransmitFile and DisconnectEx)
2. accelerated kernel-based file transmission (through TransmitFile)
3. async accept-with-data (through AcceptEx)

When any one of these were incorrectly implemented by a network stack
driver, DisableWin32AcceptEx (and now AcceptFilter none) was necessary
to work around the broken driver.  That feature has always been a gross
hack around what should "just work".
