|-
|A. Multiple Shadow Roots   
|Remove, replace with slots   
|Remove for v1   
|Remove if contentious in v1   
|Remove for v1   
|Remove
|-
|B. Default value of closed shadow root   
|Prefer: default to closed; require explicit choice; default to open; only open   
|(Same preference order as Apple)    
|Questions about implications; want "closed + isolated", not sure if we also need a "simple" closed mode   
|Need closd but not isolated, prefer open by default; will give up on this if there's consensus otherwise
|Will have both open and closed in v1, must be explicitly declared
|-
|C. The imperative distribution API   
| Want this, but not required for v1; want to discuss distribution model for v1 so we don't foreclose good design for v2   
|Want this, but could wait until v2   
|API can probably wait until v2   
|API can probably wait until v2   
|Ryosuke/Dimitri will drive a proposal by July 13
|-
|D. Separate Event Retargeting   
|Should be separated, don't have strong feelings about the default, should decide in v1   
|Should be an option in v1 tied to open/closed   
|Want to clarify retargetting, not sure if retargetting is sufficient   
|Okay with this, but haven't seen the need   
|no separation--always retarget. event.path becomes event.deepPath modulo closed shadow tree nodes, event.pathThingy reflects local tree/document
|-
|E. Shadow boundary-piercing combinators   
|Must not work in closed mode; think named parts is better model   
|Would like to postpone piercing to v2   
|Would like a named parts model   
|Think piercing was a mistake, should be removed   
|Remove
|-
|F. Slots Proposal   
| Proposed it   
|Like it   
|Like it   
|Opposed   
|Blocked on C
