I am still uneasy about that. Selectors feel like making the parser more
complex, and also there is the issue of self-documentation.

When someone reads a concat script and see "metadata foo=bar", unless they
already know exactly the directive, they will take a guess at what it does,
and since packet metadata is rare, especially packet metadata that is
duplicated over all the packets, they will probably not guess right.

I really think a more specific name would be useful.

This is an usability issue, though, so my role as maintainer is not very
important: let us ear advice from other people.
