Ah, ok.

According to that commit message, a replacement with MAC80211 support
is available at https://github.com/chunkeey/rtl8192su
But development on it seems to have stopped some years ago.
Is there any specific reason for this?
I have no clue on wireless development, so if I'm willing to test this
driver and provide feedback, would someone be interested and may help to bring
it upstream? Or doesn't it make sense to invest the time in that?
