Maybe I'm missing something, but it seems like the Sphynix markup is just a different form of inline text markup compared to DocBook XML that the current manual is using? Also, we already host the manual repo in Git, and automatically build PDF, HTML, and ePub formats.
My main thought about moving to a wiki format is that this makes it easier for users to contribute to the manual, since the text could be edited "in place" in a web browser. Hopefully that would reduce the barrier to entry, and more people would update the manual and improve the places where it is outdated.

We started with DOxygen markup for the code (I don't know why it wasn't the same as the kernel), but it would probably be possible to write a script to convert the existing code markup to Sphynx if we wanted.

Could you please explain? It isn't clear to me how this is significantly different from Git+Gerrit? It is also possible to edit source files directly in Gerrit, though it isn't clear to me if it is possible to _start_ editing a file and submit a patch vs. being able to edit an existing change. In either case, one still needs to use the inline markup language. Does Github have a WYSIWYG editor for the manual?

I'm not necessarily against this, but it would be a considerable amount of work to convert the existing manual, and there would have to be a clear benefit. Do people thing that the Sphynx markup is much easier to use than the DocBook XML? I don't think we use many unusual features in the XML.
I guess the other important factor would be whether there are people interested to do this work? I contribute to the existing manual when I get a chance, and don't find the XML very hard to use, but if converting to a new format would convince more people to contribute then this is something we should consider.
