These things are far too hard

Ok, so I know that you can link to RSS feeds via your HTML using

<link href="" rel="alternate" type="application/rss+xml" title="" />

but since we’re already using starting to use robots.txt files to reference our sitemaps like so:

Sitemap: <sitemap_location>

why not use it to reference our RSS feeds as well? It would be trivial do something like this in a sitemap:

RSS: <feed_location>

Thoughts anyone?
