Who owns usd<->mtlx synchronization (USD observability)
Who owns the mtlx->usd conversion. Can this is separated out with formal synchronization. (Recent work from Jerry and others for component dependency logic should be discussed). Needs USD to be more open.
Who owns the usd->mtlx conversion. Is it the same as 1. (I don't think so). Needs USD to be more open.
For 3/4 can this be opened up so USD does not own this completely.
Who owns validation (USD)
Who owns reference definitions, who owns implementations (MTLX). Even USDPreviewSurface.
Who owns code generation access.
Who decides what is common material metadata. This has caused "friction" as usdshade and mtlx are not 1:1.
