Digitone clicking a bug or purposeful?

If digitone amp envelope sustain is set to 0 and release is also set to 0, the envelope clicks once the decay ends. This seems like a pretty simple thing to fix, and might confuse a lot of people as it stands. Is it on purpose, or a bug? Why not automatically set release to 1 if sustain is 0 and spare the confused a trip to google? Is there some cool, fun reason it works like this?
