Actually marking the difference more visible works several ways. It makes it easier to find what you want. But it also points out that there is more. So it attracts attention. Your “bold” suggestion might be enough.
I don’t think the products a huge problem either. I just noticed it while writing the post. And if you start marking one type you should also mark the other. On the other hand: marking them out might put attention to them. (not getting lost between updates and blog posts) That could be a service to the traders.
My intention was mostly to start the discussion and stimulate thinking about it. Because once this gets going or once you add something TeaNewSite it might become a problem.
