They’d arguably stopped some time ago. I have a Thinkpad T490s, and a fair chunk of that isn’t upgradeable without swapping a fair bit of the body.
The keyboard, for example, is a permanent part of the chassis. Replacing out requires you to swap the entire shell out.
The Ethernet port is some proprietary gubbins, because Lenovo wanted to be funny, and use the same protocols and pinouts as regular Ethernet, but used a special physical connector.
Half the RAM is also permanently soldered into the motherboard as well, so you can’t properly upgrade that either.
