> Repairability is orthogonal to reliability

This is clearly not true when we’re discussing user replaceable batteries or the like. It’s a trade off, like most things in engineering.

There are many extra ways things can go wrong by making components such as batteries easy to replace. Poor contacts, oxidation, mechanical breakage, battery compartment doors popping off, ingress of dust and fluids, looser tolerances for the batteries etc.

Nobody discussing this in good faith can deny that these issues exist.
