Those who understand the fundamentals of event handling would know better, but
doing this right could be a rather invasive change. For example: Should
`read-event' return once a key is pressed down; or should it wait until the
key has been released, and then also give both the press-down and release
times? At the moment, it just notifies the user of the key?

Because once you have sensitive to "length of press", I imagine that's just
the start of additional information you'd want about events and how they
relate in time to each other...
