Well, this commit did not actually add this header override. That's been around since some version of 1.7. We discovered the issue when Outlook users were reporting that they couldn't read RSS feeds from Elgg when the Elgg site was using SSL. That's a common use case for those using Elgg on corporate intranets. Debugging this is a pain since I don't have easy access to Outlook (and really I would need access to the major versions of Outlook - 2003, 2007, etc.). We would need to find test users to evaluate other solutions.
