I've gone to https://support.yubico.com/hc/en-us/requests/new and put
in a request to improve their devices and documentation:

----------------------------------------------------------------------
Recently, the OpenBSD project disabled OTP support from Yubikey
devices by not attaching the USB keyboard driver to matching hardware
(any USB device with a vendor id of 0x1050). They did this to prevent
accidental touches from inserting gibberish into ones typing.

One problem listed as a reason to take this rather drastic measure is
the poor way in which users have to configure their yubikeys: it
requires "buggy and fragile" tools using "crazy usb feature support"
thus making disabling OTP support "very annoying".

Those users wishing to use their Yubikey for its OTP functions are
left to patching their kernels (trivial if you know what to do, but
not for everyone).

To correct this issue, I would like to request that you make
configuring your devices simpler and better documented.

See https://marc.info/?l=openbsd-cvs&m=175518230509430&w=2 for the
commit message that described the change I'm referring to.
----------------------------------------------------------------------

Of course, just one loony customer of theirs asking for something like
this is easy to ignore.  But it's worth a shot.
