When you're designing something that sells for a dollar to retailers, eg. a birthday card that sings, your boss won't let you spend more than about 5 cents on the microcontroller, and probably wants you to spend 1-2 cents if you can.

I kind of get where you're coming from but at what point do we admit that such use cases are the fringe and not the main?

Perhaps a singing birthday card doesn't need to format strings.

  How else would you get nice looking logs for debugging it?

    Using log4c

Sure, but such extreme use cases are rare and don't need to be constantly brought up.

  Even on larger microcontrollers you often have to write a bootloader...

    Very occasionally I guess. They're almost always bare metal.
    - cozzyd 2y ago
      You still want a bootloader to support firmware updates, typically in the first 8 kB of flash or something like that.

        Good point. I guess don't use `fmt` for that...

    Ok but most of these use cases don't link to the standard libs anyway, even if you're writing a C program.

> When you're designing something that sells for a dollar to retailers Then you shouldn't prioritize compatibility with 1980s Unix code, which is what C++ is for.
