I'm one of those who responds with a thank you or precedes with a please. I don't see that as extraneous or out of line, but I've sure met a few who had a fit because those "extra words" were apparently just too much to handle.
Guppy,
Yeah, today people in aviation get excited over immaterial things and yet blissfully ignore very important operational concepts if they're not explicitly written as sops---the answer--- longer more confusing procedures---to create higher risk of RWY incursions
OldFella,
the geometric definitions haven't changed, just the perfermence requirements along the length of the defined 'sectors', so you're absolutely correct
Thanks,
