> They've always displayed that way. You never see one feed mixed into another feed. This problem can't arise in RSS.
All readers I know have the option to display all feeds chronologically, or an entire folder of feeds chronologically. In most, that's the default setting when you open the app/page.
I always use it like that. If I'd want to see all new posts from a single author, I might as well just bookmark their blog.
> I never encountered it in Google Reader
It was the default view in Google Reader, the "All Items" view.
A mix of all feeds, ordered chronologically, is the default view in tt-rss, miniflux, inoreader, feedly, netnewswire, and all RSS readers I've ever seen.
It's also what "syndication" means.
For your weirdest claim:
> syndication noun
> syn·di·ca·tion
> the act of selling something (such as a newspaper column or television series) for publication or broadcast to multiple newspapers, periodicals, websites, stations, etc.
>> the syndication of news articles and video footage
( https://www.merriam-webster.com/dictionary/syndication )
The "syndication" in RSS refers to distributing the same content to many different readers.

> This article provides a simple guide to using RSS to syndicate Web content.
Note that this is a guide to creating an RSS feed from the publisher's perspective. It is not possible for two feeds to be displayed together, or at all, on the publisher's end. How do you interpret the verb syndicate?

The option might exist. It was certainly not the default in mainstream readers in the past and it still isn't now. I never encountered it in Google Reader (as mainstream as it gets), or in Yoleo (highly niche), or in Thunderbird (also as mainstream as it gets).
Whether a bunch of unused projects make something strange the default doesn't really have an impact on the user experience. This is not something you can expect to encounter when using RSS.

That approach will fail for two obvious reasons:
1. The bookmark is not sensitive to new posts. When there is no new post, you have to check it anyway. When there are several new posts, you're likely to overlook some of them.
2. Checking one bookmark is easy; checking 72 bookmarks is not.
