Should Hugo hidden param hide a page from rss and other public things?

[aormsby]

I was struggling with an issue where I wanted to host a document on my website, but I didn't want it to be accessible by normal navigation. I wanted it available only by link.

That's easy enough - just throw a page into /content/my-private-folder/ and don't add site navigation to it anywhere.

But a problem I found is that the document still appeared in the rss output, an undesirable behavior.

My quick solution was to use Hugo's built-in hidden = true param to the front matter of the page and add a check for the param in the theme's rss layout. Like so --

 {{- range $pages }}
    {{- if and (not .Params.hidden) (ne .Layout `search`) (ne .Layout `archives`) }}
    <item>
       ... item rss info here ...
    </item>
    {{- end }}
    {{- end }}

Is this hacky, or would this actually be a decent solution for the theme?
And are there other locations that hidden should provide this kind of behavior?
