I believe we have differing views on what the "bedrocks" are allan.
I have also never come across anyone in my line of work who carries the attitude of "close enough is good enough". They wouldn't be there if they did.
I feel from reading through your threads you are underestimating people and labelling them based only upon how converse with the English language they are.
Standards in writing do not link directly to standards in flying, weapons operating, air traffic controlling, shelf stacking or many other things for that matter. There is a line between required knowledge/pedantic...I will leave you to decide what side you'd rather be on.
