of course it would be an expense for the producers, and they have zero incentives to do so when even the niche that could have likely to be asking for it and buying from the few producers who did decided to ask for silly “proprietary firmware on a read-only chip” instead.

¹ availability of building tools etc. included

Most of the embedded firmware hidden out of sight and often not even upgradeable is tiny tiny embedded sequencing and the like or a deeply embedded 8051 running a 40 byte program because it was simpler to paste that in that write custom logic for it
