I just checked and I’ve had 3 hits for my blog’s RSS feed from a legit-looking browser user agent string this year. Almost literally no one reads my site via RSS in the browser. Quite a few people fetch the feed from separate clients.

I wouldn’t spend 5 minutes making that feed look pretty for browser users because no one will ever see it. I don’t know who these mythical visitors are who 1) know what RSS is and 2) want to look at it in Chrome or Safari or Firefox.

You are absolutely right!!! But...

What about people who don't "1) Know what RSS is"???

And what if you could make it friendly for them in 4 minutes? You could by dropping in a XSLT file and adding a single line to the XML file. I bet you could do it in 3 minutes.
