[Elecraft] A question about QRQ

A question about QRQ mode . . . 

I recently read a comment about the fact that QRQ cannot be used when the K3
is operating in RIT, XIT, or split, nor with DSP shift.  Because I believe,
though I am not certain, that the discussion was about whether this
incompatibility exists in the K4, I was curious about why it matters.  When
the K3s came out, and the new synths were made available for the K3, QRQ was
no longer necessary for even very high CW speeds.  If that is so, why would
there be a question about such a limitation on QRQ in the K4?  Does QRQ mode
have advantages beyond the fast QSK now built into the SOP system?
