This is what I'm going to use it for. It may not work for the rest of you, but I'm putting it out for your consideration.
Going to CDG in July. Based on two things (1) I know the plane will be packed and (2) had a horrible experience two years ago (pre E+) with scary old guy in the next seat staring at me all night and on the return a restless college kid elbowed me the whole way. So ...
I'm going to book two seats for myself - one using the cert. Then I can assure myself some P&Q and elbow room. Relieve myself of the suspense of who I'm going to have sit/sleep next to. Just pop that armrest up and hunker down for the night.

Sure it'll be more expensive buying H than V/W but worth it for me. (Am I'm hording my SWUs for some trans-pac flights.) OK, just found out the H fare happens to be the lowest fare for my dates so it's a wash on the money.
