I think the resulting change of the visual order will surprise the
users. It also complicates implementation, which for me is an
important downside.

For now, I have only implemented strictly logical cursor motion. That
is, when the next character in the logical (a.k.a. reading) order is
far away on display, C-f causes the cursor jumps to that place, then
subsequent C-f's cause it move to the left. With this cursor motion,
invisible text in a bidi buffer behaves exactly like it does in Emacs
23.
