[Elecraft] KX3: Direct keyboard interface?

[Andrew Moore]

>From the KX3 data sheet:

     "Built-in PSK/TTY decode/encode allows data mode operation
     without a PC; transmit in data modes using CW keyer paddle"

Was a direct keyboard interface considered for the KX3?  Could serve data
modes (including QRQ CW) well, but could be more power consumption and
feature creep.  USB interfaces seem compact and easy on power, but I realize
there's more to it than that.
