Fund: Why Iterable / AsyncIterable are not valid body?

What would you like to discuss?

Hello,
Currently, the request body option can be, among others types, Generator / AsyncGenerator:
https://github.com/sindresorhus/got/blob/a7b5aec57a0245cafbd21696d52cd6bd6c95628a/source/core/options.ts#L1306-1311

These bodies are used like anything implementing the Iterable / AsyncIterable protocol, via a simple for await..of loop:

got/source/core/index.ts

Lines 969 to 980 in a7b5aec

    
           } else if (is.generator(body) || is.asyncGenerator(body)) { 
        
           	(async () => { 
        
           		try { 
        
           			for await (const chunk of body) { 
        
           				await this._asyncWrite(chunk); 
        
           			} 
        
           			super.end(); 
        
           		} catch (error: any) { 
        
           			this._beforeError(error); 
        
           		} 
        
           	})();

So, the question is: Why not using the more generic Iterable / AsyncIterable instead of Generator / AsyncGenerator, as the differences should be very minor? Is there a limitation somewhere, preventing to do that?

Another benefit would be supporting the web ReadableStreams directly, with no prior conversion.
