Reserve them to HTTP/2 alone. The ALPN sets are going to leak into the regular namespace, and vice versa. Whether or not a particular header is pseudo will be just one more point of confusion.

It would be nice if headers used for routing were segregated from others. This is already a distinguishing feature of the existing pseudo-headers. This doesn�t really dictate how extension should be accomplished, but more regulatory control over validity would help maximize the semantic value of the distinction between pseudo and normal.
