Importer Options for New bloggers

I found this post:
https://premium.wpmudev.org/forums/topic/import-for-regular-user-is-not-working-cannot-import-xml-file-from-other-wordpress#post-42565

But they only talk about importing from wordpress, super admin has
Blogger Install the Blogger importer to import posts, comments, and users from a Blogger blog.
Blogroll Install the blogroll importer to import links in OPML format.
Categories and Tags Converter Install the category/tag converter to convert existing categories to tags or tags to categories, selectively.
LiveJournal Install the LiveJournal importer to import posts from LiveJournal using their API.
Movable Type and TypePad Install the Movable Type importer to import posts and comments from a Movable Type or TypePad blog.
RSS Install the RSS importer to import posts from an RSS feed.
WordPress Import posts, pages, comments, custom fields, categories, and tags from a PIBN export file.

new bloggers dont have that list, way to enable?

i found this as well:
http://wordpress.org/support/topic/menus-and-import-tools-not-displaying-wp-30-ms

"In looking at import.php, it sets this conditional before the list of importers is displayed:

if ( current_user_can('install_plugins') ) "

if i delete that line will it enable for everyone?

thank you
