I agree wholeheartedly, but sadly you should know that Apple is going to take the rest of the lineup down that road. When the 17" comes back, Apple would have basically sealed the entire thing shut, and may even leave off the screws on the bottom case.
How would Apple technicians open it up to fix it then? That hardly makes sense. Even the new RMBP is easily serviceable by Apple technicians. The only tricky part is the battery, but if the diagnostics reveals it is in need of replacement, then they don't have to worry about puncturing it when removing it since the battery is deemed defective anyway. iFixit couldn't remove the battery since they didn't want to damage the battery, obviously that doesn't apply to the techs at Apple. Changing the logic board or SSD is fairly trivial though, just need special screw drivers...
