Feature suggestion: Have an option to block entire videos that serve purely as a marketing operation

[bag-man]

I've been thinking it would be great to have an "extreme" mode that would remove flagged videos from YT homepage and subscription feeds. This could be used to remove content that is purely marketing exercises. There is a lot of content like this, and some of it can be quite subtle. Nothing quite like realising you are watching a glorified infomercial five minutes into a video...

Would anyone else have any interest in such a feature? I'd be happy to work on it, though I'm a backend developer so wouldn't be so good at the FE side.
