If I may make a minor suggestion...

If you're going to throw brickbats at each other, that seems to be more appropriate to private exchanges. 

In 6man, there is a discussion regarding draft-ietf-6man-mtu-option, which looks at the issue of extension headers, and - based on data - makes suggestions of how one might use them in a manner that is not filtered by the network. Their approach seems to not start from "let's deprecate everything" or "any opinion that disagrees with mine is idiocy". Frankly, I think there might be value in it.
