Yep. When the devices get older, I usually upgrade RAM (or install an SSD on very old hardware). Sometimes I even install a new battery.
And that's the thing: I never ever had any issues doing this. Even the internal battery is just screwed in and connected with a removable plug.
While the Framework laptops are conceptually great, I just don't see the use case in my world. It's also pretty much vendor lock-in with the modules.
