To me this distinction is what makes consciousness distinct and special. I think it is a fascinating consequence of a certain pattern of interacting systems. Implying that conscious feelings occur all over the place, perhaps every feedback system is feeling something.

This sounds like the point Pinker makes in How the Mind Works - that apart from the problem of consciousness, concepts like "thinking" and "knowing" and "talking" are actually very simple:

(...) Ryle and other philosophers argued that mentalistic terms such as "beliefs," "desires," and "images" are meaningless and come from sloppy misunderstandings of language, as if someone heard the expression "for Pete's sake" and went around looking for Pete. Simpatico behaviorist psychologists claimed that these invisible entities were as unscientific as the Tooth Fairy and tried to ban them from psychology.

And then along came computers: fairy-free, fully exorcised hunks of metal that could not be explained without the full lexicon of mentalistic taboo words. "Why isn't my computer printing?" "Because the program doesn't know you replaced your dot-matrix printer with a laser printer. It still thinks it is talking to the dot-matrix and is trying to print the document by asking the printer to acknowledge its message. But the printer doesn't understand the message; it's ignoring it because it expects its input to begin with '%!' The program refuses to give up control while it polls the printer, so you have to get the attention of the monitor so that it can wrest control back from the program. Once the program learns what printer is connected to it, they can communicate." The more complex the system and the more expert the users, the more their technical conversation sounds like the plot of a soap opera.

Behaviorist philosophers would insist that this is all just loose talk. The machines aren't really understanding or trying anything, they would say; the observers are just being careless in their choice of words and are in danger of being seduced into grave conceptual errors. Now, what is wrong with this picture? The philosophers are accusing the computer scientists of fuzzy thinking? A computer is the most legalistic, persnickety, hard-nosed, unforgiving demander of precision and explicitness in the universe. From the accusation you'd think it was the befuddled computer scientists who call a philosopher when their computer stops working rather than the other way around. A better explanation is that computation has finally demystified mentalistic terms. Beliefs are inscriptions in memory, desires are goal inscriptions, thinking is computation, perceptions are inscriptions triggered by sensors, trying is executing operations triggered by a goal.
