Honestly, I now think that the main reason was different. I was fed up by my Macbook Pro's butterfly keyboard and started working on Macbook Air '15 again at the end of 2019. And in three months I was increasing annoyed by our site loading time.

And then it hit me. MBA is not the slowest laptop out there. It is much worse for a large part of our users.

This is where I started thinking we should jump off the hype ship. :-)
