Why do i have brltty installed on the Pc?(Braille display driver for Linux/Unix)

[linub]

according to this person it’s related to QEMU

[Stable Update] 2020-09-08 - Kernels, Mesa, Browsers, KDE Apps 20.08.1, Systemd, LibreOffice 7.0.1, Deepin

Also upgraded on KDE “So far” no issues. However the during upgrading I got [ALPM] warning: directory permissions differ on /var/lib/mlocate/ filesystem: 755 package: 750 This warning seems occasionally reported in update threads. Not sure if it’s an issue or not.

Also, QEMU requires a Braille display driver.

I find it kinda weird that qemu has brltty as hard dependency while I’m sure not many people will use it.
