Thank You for such a well detailed and rich response, I have read and understood it in its entirety.
Your key points with past evidence — that they probably won't take any action and don't see it as a problem, make a lot of sense.
And your right its hard to tell what they do in the future, who knows maybe in a couple generations they could redo the whole height/weight/scale system lol.
Some will like having a mini mark effort free for their pokemon, and I guess others who want variety can just reload from bank to home to reroll.
