Seeing the Magento market share brought sweet nostalgia from the 2010s era. For a brief period of time it was all the rage in PHP commerce. It was seen as more professional than a WooCommerce setup (performance and bugs aside, I guess).

Magento 2 released and it had a better aesthetic, but it was more of the same broken ideas no one wanted to work with. Why the team went with a fresh take on the old XML-based configuration is beyond me.

Clients I worked with passed on Magento 2. Somewhere in here there is a lesson I can't articulate :-)
