PIN Protect Access to Individual Channels (Parental Control)

Hello - This has been requested 4 years ago, with absolutely no reply from ROKU. Has there been any consideration by the Roku Development Team to add password protection to accessing individual channels? For example, asking for a PIN when accessing YouTube? It would be a great addition to Parental Controls and should be relatively easy to implement. Right now, my only choice to keep a child from accessing a particular channel is to uninstall it --or take the remote away! Any comments/questions?
