r.reclass doesn't read or write raster data, so the region doesn't
come into it.

Similar issues apply to r.info, r.support, r.compress, r.null,
r.timestamp etc.

The region only matters for modules which read or write raster data. 
This includes most (but not all) r.* and i.* modules, as well as some
other modules (e.g. v.what.rast).
