llmd-fs-connector==0.22 (llm-d v0.8 / vLLM v0.22) is the final release of
the standalone llm-d FS connector. The filesystem offloading logic is now
upstreamed into vLLM as the FS tier of the multi-tier offloading connector
(TieringOffloadingSpec); all new features and support continue there.

Add an [!IMPORTANT] banner to the connector README and a short note in the
root README's Connectors & Utilities list, linking the vLLM KV offloading
guide (vllm-project/vllm#44415).

@yuezhu1 confirmed the Haifa team is retiring the
MultiConnector + llmd_fs_backend deployment shape (Path A) in the
near future, in favor of the upstream-canonical TieringOffloadingSpec
shape (Path B). vllm-project/vllm#41735 already upstreamed the FS
storage code; vllm-project/vllm#44415 (merged 2026-06-09) adds the
end-user usage docs for it. With Path A no longer a viable migration
target, the RFC is narrowed to a single M1.5 path and the Path A
scaffolding is removed.

Path A removal:

- §4.3 (was §4a): single M1.5 row (D↔H↔FS/obj via SpyreTieringOffloadingSpec
  + tiering/{fs,obj}). Path A row, the lengthy Path A vs Path B prose,
  and the SharedOffloadRegion Path-B-only carve-out all removed.
- §3.5: llmd_fs_backend reframed as historical context only. Note
  added that maintainers are retiring it; this RFC does not target it.
- §6.4 / §10 Q6: drop Path-B-only qualifiers (Path B is the only path).
- §10 Q7 deleted entirely (existed only to gate Path A).
- §7: drop test_multiconnector_register.py (was the Q7 falsifier).
- §12 acceptance: A1.5.1 is now the SpyreTieringOffloadingSpec +
  tiering/fs config (was A1.5.2 "forward-looking"); the long Path A
  acceptance with MultiConnector + llmd_fs_backend is gone. Old A1.5.4
  → A1.5.3 (engineering budget).
- §13: llm-d/llm-d-kv-cache reference demoted to "historical context."

Other review-driven cleanups in the same pass (Yue's recent batch):

- §1 motivation (3388839334): added "secondary tiers only interact
  with primary(CPU)↔secondary(storage) transfers — they never touch
  device tensors" so readers don't have to trace why no per-tier code.
- §2 non-goals (3388886266): removed; items already covered in §11.
- §4.3 NIXL out-of-scope subsection (3389029011): removed; covered in §11.
- §4 numbering (3389055734): "§4a" → "§4.3" now that the NIXL slot
  freed up. Subsequent §6 subsections renumbered consistently
  (6.3a → 6.4, 6.4 → 6.5, 6.5 → 6.6).
- §9 PD-disagg paragraph (3389364673): moved into §11's PD bullet.
- §12 A1.3 format.sh (3389412218): clarified inline that format.sh is
  the repo lint wrapper around uvx prek.
- §12 A1.5.1 PYTHONHASHSEED bullet (3389437690): removed — that
  requirement is vLLM's contract, not this RFC's to test.
- §13 (3389446222): added vllm-project/vllm#44415 (upstream user-facing
  multi-tier usage guide); kept llm-d-kv-cache reference but reframed
  as historical, per the Path A drop.

Net: 31 insertions, 94 deletions. Doc is materially shorter and
points at one M1.5 path instead of two.
