Query limit in node_admin_nodes() function still hardcoded to "50"

The number of nodes shown on the content admin page (admin/content) is still hardcoded to the value "50" in node.admin.inc:

$nids = $query
    ->fields('n',array('nid'))
    ->limit(50)
    ->orderByHeader($header)
    ->addTag('node_access')
    ->execute()
    ->fetchCol();

This is especially bothersome when trying to delete lots of content (e.g. after importing test data).
See #7743: let admins mass delete nodes for this feature request since ancient times.

I once wrote a small core hack to make this setting configurable: "Increase the number of nodes per page when administering content".

It would be great if this would become a core feature some day.
