Explicitly deferred / out of scope
These are not part of Phase 7 (or were pushed to later):

Design non-goals (Track F)

Magento-style layout.xml merge tree
Visual drag-and-drop page builder
Full DOM reordering by plugins
Phase 7 out of scope

Runtime .so plugin loading
Low-code rule engine
Replacing catalog attributes for standard merchandising
CDN upload pipeline / admin asset editor
Hook debugging UI
Freezing the entire plugin API (only hooks + slots are Stable v0)
Unscheduled backlog (Phase 7+)

Admin grid UI for field definitions (API exists from PR-702)
plugin.App.Extensions() SDK helpers
Variant/customer extension scopes
Custom widget per field code (plugin hook later)
Incidental deferrals from shipped PRs

PR-712 scoped out partials → done in PR-713
PR-714 scoped out new anchors → PR-715
engine.go template file reads still in domain (noted in review; would need a content-provider port)
Bottom line: Tracks A–E are complete and usable. Track F is ~40% done (4 of 10 PRs). Phase 7 closes when 715–720 land (or the stretch items are consciously dropped). Next up: PR-715 — remaining page anchors.
