Hello,
You are right, it is rare to find music in this key, but there is music written in this key. The reason why it's not so common to find is because this key requires all notes to be sharp. So composers would try to avoid this key because it could be fairly harder to read for the average musician. I hope this helps.
Best Regards,
Angel
