Remove 'blogroll' from the import options

[Ipstenu]

Now that we've dropped links (#21307), we shouldn't encourage importing them. It'll just confuse the newbies.

This will require a change to ​http://api.wordpress.org/core/importers/1.0/, so while we can clean up /wp-admin/includes/import.php (attached) it won't matter till that's scrubbed. Maybe upgrade that to 1.1 so people who are on older WP are left alone?

removing opml from the import file

Seems sensible to me. I'd be tempted took hook display to whether they have the plugin enabled or are still running the legacy version though.

Replying to Ipstenu:

I planned ahead. The endpoint receives the version number. :)

We talked about this in the weekly design triage and would encourage this to happen.

Reassigning the ticket to @hareesh-pillai: they asked to own the ticket to help it to go ahead.

Created ​#meta4706 for the API change.

With 5.3 Beta 1 shipping today, I'm punting this to Future Release so as not to clog up the 5.4 milestone. However, @hareesh-pillai as the ticket owner feel free to move to 5.4 if you feel comfortable committing to resolving this fully then... thanks!

I've committed the change on api.wordpress.org to not show it in 5.3+. The list in Core is only used as a fallback in the event the API is unreachable (and to allow translations of the importer names/descriptions)

What's the opinion here - Should I leave it as-is, revert, or bump it to not show for 5.4+ instead?

(edit: I had the tabs open and hadn't refreshed the Core ticket, so I wasn't aware it had been bumped at the time)

Testing this applies cleanly and the unit tests run. The Blogroll entry already isn't showing due to the api change so remove this will have no visual affect. Marking for commit to clean this up in core.

In 47227:

Import: Remove "Blogroll" import option (for links in OPML format) from the list of popular importer plugins.

Link Manager is disabled for new installations since WordPress 3.5, so core should not encourage importing links.

See ​#meta4706 for the corresponding WordPress.org API change.

Props Ipstenu, hareesh-pillai, DrewAPicture, nacin, karmatosed, dd32, garrett-eclipse.
