It never disallowed it, it is simply a flag for the atkbd(4) driver.  You can
always tweak it by turning off flag 0x1 on the atkbd0 device via a custom
kernel or using a userconfig script.  However, by default keyboards are
actually probed and not assumed present on 4.3, so hotplug of a keyboard if the
keyboard was not plugged in in 4.3 will not work out of the box.  Note that
hotplug of USB will work.  A real fix would be to have the atkbdc0 driver
attach a atkbd0 device in the case that a keyboard interrupt comes in (i.e. on
the first keypress after plugging in the keyboard).
