Embeds: Who put this REST API infrastructure in my WordPress?
Well, while it's here, we probably should make use of it. The oEmbed endpoint now uses the REST API infrastructure, instead of providing its own. Props swissspidy. Fixes #34207. Built from https://develop.svn.wordpress.org/trunk@35436 git-svn-id: http://core.svn.wordpress.org/trunk@35400 1a063a9b-81f0-0310-95a4-ce76da25c4cd
