The primary reason for excluding SDL2 packages from the current Alpine Linux image is to maintain a smaller image size, which enables quicker startup and emulation through blink or similar emulators. Including SDL2 in the Alpine Linux image would create challenges when attempting to run graphics with the emulator.
