  • RWC changes look good
  • user/docker changes look good except for some errors in vscode that look to be due to #36539, not this PR.
  • DT changes look good

oops... I was relying on this solution because I have a Promise<MaybeList<Promise<ISymbolSearchResult[]>>>
where MaybeList is an array abstraction so I am using promise.all to remove the inner Promise I don't know what to do now to avoid using as unknown as MaybeList<ISymbolSearchResult[]> inside of my async function (which should be returning the Promise<MaybeList<ISymbolSearchResult[]>> instead of the Promise<MaybeList<Promise<ISymbolSearchResult[]>>>)
