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
