We do this basically already with motorcycles. I'm not suggesting we stop rooms from displaying the names of the people in it, but it means that you're no longer identifying people in a giant crowd without other information from cameras or through windows, people are able to move through crowded areas where people aren't paying attention with less meta, and also that people will -- by their nature -- be 'looking' at rooms and people more, which means they will be getting actual information about folks from their descriptions rather than just relying on the name.
To be clear, I am -only- suggesting stripping names out of the entering/leaving messages, not anywhere else -- I know there are code issues with having people display in room contents by shortdesc -- but I think losing the 'name' from that message would increase the sense of the world being busy and crowded immensely and cut down on a lot of smallworlding. Given that we're able to do it when people are riding bikes, it seems like it should be relatively easy code-wise to do.
