How would it be? Modders don't do any real work, the manufacturer does the support for new hardware, they never have to work by themselves to support new stuff. Years ago Marc the liar and alias Victor said they would replace cgminer, they of course never did it because that would force them to work, so stealing cgminer remains the game.

The S19i uses a different chip and demand was so low the devs skipped it entirely, that is why it has never been supported. I don't recall ever seen it shown as supported nowhere, i believe you confused yourself with the S9i.
