My point with the other communities was specifically to answer your objections above to say that those places should be called what they were not to say that they were CDPs  As far as legal designations they dont change much  When you get to local government changing is very inconvenient imagine if assuming youre in the mainland USA your state decided to declare that all municipalities were suddenly burgs even if the way they functioned was no different the paperwork would be immense  Because local government is a creature of the state a state cannot be incorrect when it declares that a specific government is a specific type therefore anything in conflict with the designation including the Census Bureau see Harrogate vs HarrogateShawanee Tennessee isnt reliable for that purpose
