The file must be contained within the package (i.e. not a remote
conditional dependency), but yes.  You use an <installcondition>  within
<phprelease>  for that task.

Use a conditional install group named "default" that requires the
default driver and renderer.

<group name="default" hint="standard Structure_Datagrid setup"> 
 <package> 
  <name> Structures_Datagrid_DriverWhatever</name>
  <channel> pear.php.net</channel>
 </package> 
 <package> 
  <name> Structures_Datagrid_RendererWhatever</name>
  <channel> pear.php.net</channel>
 </package> 
</group> 

This will be automatically installed unless the user explicitly requests
another installation group.

In other words, no need for a feature request.
