CCIE Service Provider Operations?

Hi guys,

I was wondering what CCIE SP Operations is all about. It seems the be a very strange cert. The CCIE that no one bothers with or talks about. Has anyone ever passed it? Or even taken it?

I recently passed SPv3. I'm thinking if there is a big overlap doesn't it make sense to get SP Ops too? Maybe INE could do an 'add on' for their SP stuff. It could be a nice simple path to make double or even triple CCIEs?
