Hey, Happy New Year everybody. Some SIP updates based on the discussion above:
I added v2 examples for each API to the SIP. Feedback welcome, especially on the v2 APIs that are net-new to this proposal (namely: "list backups" and "delete backup"). I've also amended the backcompat/migration section to mention Jan's suggestion that the "incremental" features be exposed in the v2 API only. Though it's unclear to me whether that's still something people want since it turns out that we'll still have backcompat concerns with the existing v2 backup/restore APIs. So I've held off from removing/replacing the original plan.
