<p>Agree. Although osmosis is somewhat slow, it used to be a valuable option to set up an OSM clone based on some country extract. In particular, creating identical user accounts (with fake email addresses) and object ids like on osm.org is really helpful. Hopefully we can somehow migrate this osmosis feature to a new tool, too.</p>
