I'm not surprised that our American friends have weighed in with their own version of The Queen's English. It is, of course, a reflection that some parts of the American version of English are actually more linguistically pure [i.e. dating back to the 17th Century] than that which has subsequently evolved on this sceptre'd isle [please note the possessive there

].*
I have always worked in accordance with the principles of
JSP 101 which could be summarised as 'keep it simple'. Extraneous or optional apostrophes do not conform with that tenet.
"Sceptre'd isle" ain't a possessive! But I agree with your tenet.
