DMG actually not installer itself think about more like iso file image where system mount dmg file and u can run apps from there by double clicking them without installing or u can drag and drop content of dmg file to applications folder and become it like “installed”
Installing a downloaded app by dragging the .dmg into your Applications folder.
Just why? What is the case where I download an app installer, execute the installer, but don’t want the app installed?

It’s closer to a zip file than an installer. That one never bothered me at all
