I agree. I have even replaced the screen on my x280 to a IPS screen (because the old one was a crap TN screen) and the storage.
I wish newer machines were more repairable and I would buy a framework if I could afford it and if they had more ports. Fortunately most machines don’t break that often and very rarely is it in a part that couldn’t be replaced by a skilled technician (excluding some shitty products like Apple computers). Most business tier laptops like Lenovo ThinkPads and Dell Latitudes (5xxx and 7xxxx series at least) are fairly repairable and durable.
Upgradability is also great but doesn’t make a lot of sense to worry about when the machine is a decade old and still crap performance wise even if you gave it a few more GBs of RAM. You can’t really upgrade anything beyond storage and ram in any laptops unfortunately.
I wouldn’t consider a decade old computer no matter how repairable, durable, or how upgradable it is unless I worked exclusively in a TTY or some shit and I believe most feel the same way.
You do you, but I still don’t think it’s a good suggestion for someone that just needs a computer. Especially when they want good battery life and compactness. Neither of which computers that old are good at.
