You're deluding yourself if you think there aren't significant tradeoffs in making a device serviceable without specialty tools. "Bulkier" is a common one, but you could keep the size down by sacrificing performance (in order to keep the heat down and/or to make do with a smaller battery). I'm not sure exactly what kinds of tradeoffs are being made, but (for example) according to Tom's Hardware, the Framework laptop has half the battery life of the MacBook Air.
