They could easily let you accomplish this by just giving you an option to actively seek out this content by giving you a "What else is like this?" button that takes you to a 'related videos' page. The problem when it just puts it all in a single recommendation feed is that that feed more-or-less presents itself as "here's what the world is talking about" rather than "here's a bunch of stuff that conforms to the biases and ideological filters of the stuff you've been watching lately." It creates a solipsistic worldview if you're not aware of what's going on.
