Well I understand that you are talking about how people in the interested but concerned group are affected by the "unfinished bridge", we should note that there are still 13% of people who would use an unprotected bike lane.
Further, the unfinished bridge helps build up to addressing the network problem, with less investment than a protected bike lane, we can move from 7% of cyclists using the system to 13%.
Finally, this is a chicken and egg sort of problem. People need to cycle to make the bike lanes worth it, but no one will start cycling without any bike lanes. If society deems more cyclists to be a social good, we need finished bridges, but unfinished bridges are still better than no bridges.
