Would I do everything that is advised I would die 20 years ago from sad life ;)
Little know, tires can take 5 times the rated load when rolling with low speeds.
In driving it is the heat that comes from too much flex that is killing tire cords.
So I would not worry about putting much weight on tire when parking, but that might affect comfort.
I am too lazy to put planks under both tires, but you do a test and let us know?
I don't carry blocks, but DIY all the maintenance, I know my parking brakes are in excelent condition.
