I'm pro genetic modifications for these sort of (slight) changes. We live in entirely different environments and our baselines to be healthy makes sense to me. Of course the next step always seems to be "make superhuman soldiers" or "designer babies".

Each of your muscle fibres contain what is known as myonuclei. These are a structure within the muscle cell that act as the ‘brain’ of the cell – in this manner, they are what tells the muscle fibre to grow in response to strength training.
Interestingly, when you undergo a period of strength training, you see an increase in the number of myonuclei within your muscle fibres.
And this increase is permanent.

I had a child, took a year off lifting, or basically doing anything but walking, I didn't lose much mass or strength and it hasn't taken me long to get back where I was, I'm pretty happy with the current design, maybe you should train more so you actually have some muscle in case you do need to spend a few weeks in bed?

You're arguing against a strawman. I'm not complaining about working for self-improvement, I'm complaining about how muscles shrink away so rapidly when not in use. Look at what happens when people are bedridden for a few weeks, that is not good design!
And I'm not saying people should automatically look like body builders, I'm saying the baseline should be a healthy level.
