As with many things in an Arch derivative, the packages you install are your choice.
In the case of this package, it is only needed for VAAPI support for a specific set of iGPUs,
$ pacman -Si intel-media-driver
Repository : community
Name : intel-media-driver
Version : 22.4.4-1
Description : Intel Media Driver for VAAPI — Broadwell+ iGPUs
Therefore, there’s no reason it would be installed automatically on any system.
