I don't mind a bit of formality. Sometimes I think that our modern society takes too much of an informal approach to too many of our social interactions these days. My thoughts on the matter are that if Brothers use the address "Worshipful" since I am a Past Master then I will take it as it should be meant, a descriptive term indicating my dedication to the Craft, having served the Order as the Master of a Lodge of Freemasons. Never to mean that I believe I am better or higher than another Mason!
Look at it this way, if you had the opportunity to meet a former POTUS you would most likely address them as Mr. President, correct? Now, how much more important is a Brother Freemason?
LOL The term can be seen as merely a form of respect for service.
Either way, that is interesting that Kentucky has codified the forms of address for WM's and PM's. What does it say about Past Grand Lodge Officers? Does the same apply or are they just Brother as well?
