I haven't read the thread but there are things that running single chainring enables which can result in quite a few watts saving for those interesting in TT riding. The gains are more to do with being able to narrow Q-factor than the actual removal of a ring from an existing set up, the latter having a very limited benefit - I guess it might cough up a watt or two. Ruin aero? No. Potential tiny gain, yes. Narrowing Q factor though can be somewhat more worthwhile for aero gains.
I'd still run a chain guide for the front though if not riding a fixed gear.
