Hi Wythe,

Since you found this example and they seem to be using github issues to
document shortfalls and bugs - maybe you could document your finding. In
general, reflecting unknown options and flags is a very bad practise -
as the semantics of these extentions are unknown. And even a stateless
SYNACK reflector could simply remove unknown things and not incur too
much or a performance penalty.

Maybe you want to give some feedback along these lines to the
developers/maintainers of this particular codebase.

Thanks for bringing it up!

Richard
