Even here, I must be missing something, as I cannot see the issue.

If I need to fetch from someone who is tracing metadata, then there are 2
alternatives:

1) I am fetching only for myself and I am not interested in metadata at all.
All I need to do is to fetch. With this I will fetch a repository with
one/some extra file/files (e.g. .helper-metadata).

2) I am interested in the metadata tracing (e.g. to interact with
my origin). Then it is sufficient to first install the same set of
metadata tracing helpers as my origin and after that to do the fetch.
With this I will fetch a repository including the traced metadata files
just as above, yet these would be immediately be used by the helpers
through the hooks. For instance, as soon as anything gets checked out the
proper metadata can be applied.

Obviously, before installing any hooks, I should trust their origin.  But I
believe that if hooks get this kind of usage, rapidly we will see
the growth of trustable "standard" hooks-bundles for many tasks.
