Summary of discussion on Contentious Bits

The data in the following table was copied from the Summary of contentious bits document.

Contention Point	Apple	Mozilla	Microsoft	Google	Resolution
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
