Actually, it seems those rules change all the time. In fact, if you search the government sites about canning, they tell you not to use old canning recipes.
I agree with most of what you say there.
Are there any other myths out there you guys would like to dispel?

Let me explain my wording on that so that it is a bit clearer -
The canning/preserving rules DO change - but regardless - those rules should not be changed or modified.
As far as the "recipes" for canning go - the recipe doesn't matter - you can change, tweak, add or subtract the flavorings, and ingredients for personal preference.
But if you make a tomato based sauce - you still process it for the length of time specified - it can be a tomato sauce recipe from your great grandmother - just use today's standards for doing it.
