Zwift a Cheaters Paradise?

Zwift are making all height and weight data private. It will still need to be entered to ride, but other riders will not be able to see it. This has been done, in part, to protect those who are vulnerable to having such numbers displayed in that way. But does it actually solve the problem it tries to - given that being lighter will still be a goal for many people - even if their weight is not displayed?
And what does it mean for weight doping?
UPDATE: It seems Zwift have had some second thoughts and, for now, height and weight will STAY on ZwiftPower!
