Manage Post trackbacks within the REST API

[imath]

Hi,

I've noticed, unlike the Classic Editor, the Blocks Editor does not include a place to add trackbacks to a post. After looking more into it, I've found a possible reason for it could be that the WP_REST_Posts_Controller doesn't support adding trackbacks.

I believe it's weird the Blocks Editor includes a Discussion panel saying Allow pingback and trackbacks although it's only possible to add trackbacks from the Classic Editor.

I suggest the attached as a primarily step before working from the Gutenberg GH repo to suggest a way to deal with this feature.

In the meantime, if some of you need to send trackbacks from the Blocks Editor, you can use this ​plugin.

Howdy @imath :)
What is the best way to manually test this patch? I tried pinking from two local installs (a dev setup and an instance in a local vagrant) but couldn't see any effect.

Thanks for working on this @imath! I think this makes sense to add.

Disabling sanitization and validation by setting sanitize and validate callbacks to null shouldn't be necessary, were you running into issues without that?

This will also need unit tests.
