Stackoverflow uses Atom's author tags in their RSS feed (cf.
https://stackoverflow.com/jobs/feed). They indeed use the correct namespace for it. But currently, as this namespace is unknown, it is just added as a random extension.

My wishful expected behavior would be to fill the author information of the RSS-feed structure.

I could implement it, but I want to ask beforehand:

1. Should this be done on a case-by-cases basis, read: for the moment only for the author tag.
2. In a general way: Allow atom tags in all possible places. This will probably turn out to be quite a lot of work (and messy?)
3. Ignore it, chimera feeds are evil :)
