If it's just about keeping a link to a handful of content creators, and you aren't a multiple-hours-per-day yt addict, there is already a nice solution for that, which universally works for all web resources and is well supported by all browsers under the sun.

I'm sure thay's not ideal (e.g. not for Google trying to understand you better) for the addicts, but for the other ones, this can be the perfect solution.

I never use the bell. I just subscribe and go through my subscribed list to watch videos, and for some I add to my rss reader.

RSS works much better, and youtube still supports it despite hiding it well

I've never used a YouTube account, I've always just used the site as-is. For a (very few) accounts, that I want to know when they release a new video, I just add them to my RSS feed reader.
