Thanks for listening and I really thought the issue was overblown. Then I remembered that I actually had it replaced for a faulty spacebar at 2-months in. So this will in fact be my second keyboard replacement. The reality is that it might have been failing for a while now and I didn't notice because I only use undocked when traveling and, well, Covid. The only saving grace is that I'm not out of town working with a client due to, again, Covid.
Annoyingly, what was a purely personal machine became my primary business machine since I started working for myself, so 5-9 days of downtime for a replacement really burns. I'll use it docked until the return kit arrives and then fall back to a Lenovo Windows machine I have around.
My trust in it is gone, so I'll keep it around through the keyboard repair period, but then it's gone. I use this machine to put food on the table and it has to be solid.
