Hi,

Is there another reason for this change? It seems counter-intuitive to
avoid improving/changing something just because an OS fingerprinting
firewall will no longer recognise it.

As is, other operating systems couldn't care less about the OS
fingerprinting firewalls; they'll change things in their network stack
as they see fit.
