Having an actual mini-sata or m.2 connector won't be too taxing. But it will increase tech support costs, and lower profits from sales of new replacement machines at least.
Sad. (That's why my choice is Thinkpad T series, which is built like a tank: heavy, bulky, easy to replace any part, and hard to actually break; also, enough room for a good keyboard.)
