If hacking cartridges becomes popular enough that it impacts their cartridge sales, they might put out a firmware update that does just that, but it looks like they went with the "lazy option" first?
Daan Tech broke their firmware update mechanism for lots of dishwashers in the field by losing their keys, more than once too. I own one such dishwasher and can't update the firmware without replacing the main board. They could certainly prevent cartridge resetting in newer dishwashers.
Which is one of the main reasons to never let "smart" appliances access the internet.
