It's probably worth noting that that the "intellisense that vscode gives out of the box" is _also_ still delivered by TypeScript. Slap a `//@ts-check` into a js file and you'll find just where the typechecker thinks your jsdoc or usages are lacking or confusing (then maybe add a jsconfig with stricter settings than the default!). If you then fix those, you should be capable of getting _nearly identical_ completions in js and ts (because they really are just variants of the same language).

IMO, TS is all about static enforcement of inline documentation (types), just like how a linter enforces style. You can choose not to enforce it automatically... But at this point I don't get why you wouldn't? I wouldn't argue that style enforcement is best done by hand in the code review stage... So I don't see how further quality checks based on semantics derived from documentation would be any different.
