It's possible to read the reason why expiring was broken in: https://jira.toolserver.org/browse/TS-971 (march of this year)
The reason why we don't restart expiring was performance problems, we had a lot of queries that running longer than 20 minutes for low-zoomlevels renderings (time-out) and the Queue seems not stable. (We were too slow.)
Now (with the clustering) it seems better and the Queue is going done today. Tiles on z=9 needs very long (>600s). But it seems acceptable. --- We have now indexes for geometry,hstore and osm-id. If somebody needs index for name or ref -> please give me a signal.
It seems that we can restart the db updating tomorrow. ---- So or so I will try to optimize the rendering strategy from zoom-level 9-15. see talk-de: http://lists.openstreetmap.org/pipermail/talk-de/2011-July/087862.html

Is there a particular reason why expiry was disabled? The load seems fine at the moment, even though quite a few tiles are being rendered.
I don't know either who disabled it or why it has been disabled. Probably it had been deactivated in favour of another process...
