Google never cared enough.
This has been an issue since at least Android 4, granted some SD cards are terrible at random IO.

Spotify has a SD card feature that’s completely broken.
My Samsung camera App can’t record 4k60 to the SD card, no matter the speed.
At least the Samsung file manager handles it decently :D

Sorry, read the post wrong.
