DISCLAIMER: Arch Linux is not a beginner friendly distribution, and this is not a recommendation or good practice.
I know how to use pacman -S. I have yet to experience a Discover related issue after months of use.
You're not wrong. That said my broke ass can't afford cutting edge hardware so most of the time it doesn't matter.
When it does, I can usually compensate with either a NixOs profile install, a container of some sort (or Flatpak), or just building the emefferr from source.
