Yep! It's a feature they've had for quite a long time. I use it extensively

I didn’t know reddit accounts have their own RSS feeds! that’s awesome.

I also use my rss reader for stuff other than reddit. I prefer to have everything in one place :)

I've stopped using Reddit directly entirely and instead subscribe to the RSS feed tied to my reddit account. Much easier to quickly get through everything in an RSS reader, rather than dealing with their stupid UI that purposely puts things out of order to keep you scrolling.
