On more thing: because off the removed -d parameter, Remotes like the
Technisat TTS35AI are no longer supported, such Type of Remotes are not
recognized in /sys/class/rc/.

So I'm now the proud owner of this device.

This device is a usb dongle which is an IR receiver, but self-describes
as a usb hid keyboard device. It comes with a remote.

As far as I can figure out, there is no way to reprogram it.

So users have been re-mapping scancodes to different keycodes using:

ir-keytable -d /dev/input/eventN -c -k 0x12:KEY_F1 

However, ir-keytable was designed load keymaps for rc devices, not hid
devices. This functionality was intentionally removed, as it was buggy
in many ways. ir-keytable does not exist for remapping usb hid keyboards.

This has left some users like Ralf in a situation where they can no longer
change the key mappings for their remote.

ir-keytable is probably not the right way to do this; it has no rules to
do this from udev, for example. What tooling is there for doing this
and what is the recommended way to do this?

remapping the keys through the udev builtins maybe?
see /usr/lib/udev/hwdb.d/60-keyboard.hwdb
