fyi.opensocial.importAccountSpace

While an account's move here is pending (importAccount), bring one of its spaces, as its own server serves it: `meta`, a space it governs (com.atproto.space.exportSpaceMeta's archive), before any repo in it; `repo`, its own repo in a space it wrote in (com.atproto.space.getRepo's archive); or `blob`, one of its files in a space, before the repos that hold it. Only for whoever started the move, and only the account's own. A personalspace or memberspace policy is kept as this host's grants; one this host would not keep as it says is refused.
