Ask a parent what they hear when they hear “irreversible” in conjunction with their child. I promise nobody mistook that for “until the heat death of the universe,” but I can add a note if you really think it’s warranted.

You definitely make a good point.

But even reversible changes aren’t always “reversed”. They aren’t necessarily minor.

Sure, breaking an arm or skipping high school can be a “reversible” change. But not often not fully “reversed” and/or not done so in a negligible time frame. There are costs. Seems like biological development could be similar.
