connects #3670

@schadowfax It's a breaking change. You'll have to make this opt out. If you'd gotten this in 48 hours ago, it's maybe fine, but not after the 8.0 release.

Meh, I'll allow it I guess since it's just day 1, but we should have gotten this before.

@jeremydmiller i'm sorry i tryed when i read the possible release date but i failed to get to it in the weekend.

Glad your looking into it and considering it.

Only not sure about the documentation of the index. there is namely a =>

• metadata_index.md (can't this one be removed?)
• metadata-index.md
