I'm arguing for B.

What I care about is timeline, assets, library, keyframes, movie clips, drawing tools, text formatting, tweening and much more. All in one package, cmd+enter to see the output. Maybe even these days cmd+enter is too much, the output should be immediate and even better - live. Bret Victor would not be happy about not-live (dead!) scene. Definitely I don't want to resurrect old Flash. TypeScript is much nicer than AS3, even though AS3 had E4X which I remember to be quite powerful even compared do poor JSX.

I think you're right about missing GC and shipping `List`, `Set` etc. to the user as a part of the runtime. But, if that can chunked out and be stored on a CDN and downloaded only once for a browser session, then this problem won't hurt that much. Once GC is added to the platform I'd love to see Figma-quality reincarnation of Flash in an B-option (from your post) manner.
