How can I change the RSS URL?

If I only include in my config.toml the following chunks:

[outputs]
home = [ "RSS"]

[outputFormats]
[outputFormats.RSS]
mediatype = "application/rss"
baseName = "feed"

I wind up with no /index.html, only a /feed.xml. I had to instead specify:

[outputs]
home = [ "RSS", "HTML"]

[outputFormats]
[outputFormats.RSS]
mediatype = "application/rss"
baseName = "feed"

Which seems to do the job! The only thing now is that {{ .Site.RSSLink }} still winds up pointing to /index.xml, but this can obviously be worked around.
