Thanks for the question - these are the kinds of questions that I want to get and answers when we are deleting stuff.
The good news is that this change has no impact at all on the News or Podcasts tools - these tool *consume* incoming RSS feeds - what I deleted was the ability for Sakai to produce the list of sites at “/portal” as an outgoing feed. For example, the dream was that ools ike Google Reader
would be able to let users subscribe to a list of sites in their Sakai and merge it with other RSSS feeds. But it never worked well because login was required to get one’s personal sites, etc etc etc.. We never invested in sending things like notifications (again RSS is usually about non-login resources).
So the good news is that Podcast and News are unaffected :)
That said, a quick test of those tools and your use case on a nightly server should be quick and verify that nothing changed.
Thanks.
