I mean, it sort of does and sort of doesn't, but the hardware manufacturers just aren't used to thinking about things in the proper way. Just like the hardware is a black box with no user serviceable parts inside, as far as they're concerned the firmware (because that's still how they think of the OS and everything on it) is a single binary blob with no user serviceable parts inside, even if it's actually just linux and Android. And just like all the hardware parts are designed and qualified for a particular design, the same goes for the software: when you buy your hardware you get a software with it and that's that. As far as they're concerned it's just another component like a screen that gets customized to work with everything else and goes in the box, then is never touched again.
