That makes sense long term.

Oh, that is an interesting perspective. Here is how I arrived at the opposite
conclusion initially: Searching for 'ignore_env' shows that we care about it
as well for the index and graft paths, which are not the object store, hence
it would be better kept in the repository. (The alternative would be to
duplicate it into the raw object store, but I do not like data duplication)

But maybe it is better to duplicate this one bit instead of passing through
a larger scoped object.

I'll rework the patches.
