datalad push can only handle branches, so this is not the tool.
However, "aggregation" is also not the tool, because it only works in a "pull" fashion and, moreover, datalad will not be present in typical "webserver" setups.
Wasn't datalad push supposed to respect git-config for what refs to push? We could wrap push in this extension and pass a config override to add the desired metadata refs, I suppose.
