Cute ...
Funny you mentioned Chess, wich (aswell as any at least little complex game) had many rules added, removed, or changed during the times.
Games are adjusted, tweaked and redesigned countless times over the years.
That's why this is called "5th Edition" of D&D in case you didn't notice before.
Tweaking doesn't mean making it frictionless and surely doesn't mean "We can throw the rules out of the window at will in the mid of playing it".
Basically, this is not even close to be the strong "gothca" point you think you are making.
