✅ Viability Checklist

My suggestion meets these guidelines:

• [z] This wouldn't be a breaking change in existing TypeScript/JavaScript code
• [z] This wouldn't change the runtime behavior of existing JavaScript code
• [z] This could be implemented without emitting different JS based on the types of the expressions
• [z] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• [z] This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

I think many users find includeCompletionsWithObjectLiteralMethodSnippets super useful, I have an idea to do the same for other types.

📃 Motivating Example

declare const configureMe: (options: {
    name: string
    type: 'a' | 'b'
    enable: boolean
    otherOptions: Record<string, any>
    mixins: any[]
}) => void

configureMe({
    
})

Snippet completions described by types:

Also I think preference should be added to allow these object literal completions with snippet to be displayed above original suggestions (or even remove these original suggestion, if user really wants it) eg completionsWithObjectLiteralSnippetsNonSnippetPosition: /*default*/ 'before' | 'after' | 'remove'

Also in vscode plugin I found extremely useful triggering additional suggest widget after such snippet completion accept.

Can I try to implement this if its good?

Note: I use on a daily basis with my TS plugin: here is current implementation if someone is interested.
