If I wanted a charger with 4 ports I'd buy it. If I wanted a braided cable I'd buy it.

You really should try it. People don't know what they're missing until they use it.

I have the same experience with lots of pack-in products. One that comes to mind are camera (DSLR) neck straps. They're absolutely dreadful, and shiny advertisements to boot. At some point I tested a bunch of 3rd party ones and found how much better they are. Yet people kept acting like I'm the weird one for paying 20-50 $€£ for something that improves the experience so much.

Same thing here. If for nothing else, not including those crappy accessories just makes people think about the alternatives.

There's a reason why accessory brands even exist. OEMs actually rarely know how to do accessories well.

let's say a 0.5 to 1 meter

So FYI standard length is 1 metre, which tends to be a surprise to people when I tell them... 0.5m is super short for anything but a PC connection or powerbank. Again I suggest you try a good, soft, braided 2m cable if you charge using a power brick.

that can also do basic data transfer

What's "basic"? You know, with most phones you only get a USB2 cable (if it does data transfer at all), again showing how useful they are.

People rarely do data transfer via cable these days, and a really good USB3 cable doesn't cost 5 cents, so again to me it makes sense to just get one to your liking.
