Heads Up: Sierra installer pulled from App Store (including purchase history)

[macandcat]

Here's a warning NOT to delete your Sierra installers! Apple has pulled it from purchase histories. Apple support document linked below - the line about Sierra is near the middle of the page.
Relevant paragraph:

To reinstall Safari, Mail, the App Store, or other apps that are included with the Mac operating system, reinstall macOS. macOS Sierra or later doesn't appear in the Purchased tab. Instead, use the Search field in the upper-right corner to find and open the App Store page for the current version of macOS.

Maybe because of....

About the security content of macOS High Sierra 10.13 Supplemental Update

Fresh install of 10.11 from recovery partition logged into App Store and Sierra 10.12 is there. Same account on a 10.13 image Mac and Sierra does not show. Just adding a puzzle piece.

Looks like they're moving more and more towards and iOS style restoration path. You can't really backtrack iOS (easily)
