That will not happen. In fact, the trend is from having firmware be a part of 
the driver to having it be external.

I don't know what distro you use, but mine (openSUSE) maintains a package called 
kernel-firmware that contains all the redistributable firmware that is available 
from tne linux-firmware git tree. If that package is installed, then you do not 
have to search for firmware in most cases. If your distro does not have such a 
package, then complain or find another distro.

We can tell that you have an Intel card, but not much more.
