[Trott]

Headers have ids automatically assigned. Removed ad hoc ids using anchor
tags that aren't links.

I kind of wish we’d go into the opposite direction more often – these anchor tags allow creating permanently functional links from other websites to the documentation, while the automatically generated anchors can easily change even when only a minor change to the header text was performed and break those links. I would keep them.

I can definitely support that to accommodate links from external pages, but these were apparently created to have links from within the page, and I'm not sure we want to encourage that.

this change doesn't land cleanly on v14.x, should it be backported?
