Detents are a human factors thing; helps the user estimate the
rotation, but they have only a statistical impact on the pulse train;
they don't prevent specific states.  Code should still expect and
handle contact noise.  A way to do that is to hide the least
significant bit, so the noise that occurs does not affect whatever
you're using the data for.

For a bare encoder with A & B output only, the width of the pulses
will vary by speed of rotation; and you might be able to use the width
for something.  But it is the rising and falling edges that matter for
most purposes.
