Aren't projects like PostmarketOS upstreaming many devices? Meaning that you can then update the kernel, right?

  PostmarketOS is the mainline Linux kernel and doesn't have all the features that are needed for a proper Android phone. There are a lot of Android userspace drivers that may break with another kernel.

    Oh, that makes sense!

Custom kernels are not upgraded kernels. They usually just back port a few fixes. No custom kernel running Android has a full kernel upgrade because it breaks the KMI and kernel drivers aren't usually updated.
