I'm fine with dropping moxie now - I've never seen anybody using it and I've 
never spotted any binaries in the internet that could still be used for 
regression testing of this target. And I've also put Anthony Green on CC: 
when I suggested the deprecation and he never replied. So I think it's 
really completely unused.

I didn't add these two entries to the deprecation list, I just moved them 
around since they were in the wrong section. Both have been added by Peter 
instead (commit d8498005122 and 8e4ff4a8d2b)
