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?
