No.  It's only required for metasearch - like all the other stuff in ext-libs -
except pyspatialite.

No, it's too old in osgeo4w.

It not available or not uptodate enough on all distributions.  That why we have
it in qgis.  That's also why osgeo4w is not uptodate - only qgis would require
it in osgeo4w.  And maintaining it in both would just duplicate the work.

Well as metasearch is a core plugin, qgis should ship  everything required (or
depend on stuff that is available everywhere).  That's why all the stuff was
added...
