Looks like the intended use case here is you buy the cartridge once, and refill it, and OpenPrinter won't lock you out after doing so like HP does.

Yea, but then the print head clogs up after the second time you refill it and you buy another expensive print head + ink from HP.

Frankly, I think 99% of the reason they started integrating the print head with the cartridge was to avoid all the problems you so frequently see on printers that don’t use disposable heads.
