Short answer: No and you can stop being apprehensive about it. :-)

You will plug in your paddle [and/or external keyer and/or computer], 
and you will be sending clickless CW with full-QSK.  Had the subject not 
come up [again] on this email list, the odds that you'd ever encounter 
and notice its effects are vanishingly small unless you are a 60+ WPM 
full QSK operator.  I operate in a lot of CW contests with N1MM driving 
a WinKeyUSB at between 30 and 35 WPM, KPA500, full QSK, QRQ option off. 
  No one has ever given me a QSD.  When I've specifically asked friends 
[good CW ops] to evaluate my keying, they tell me it's great.  My "fist" 
is another matter of course. :-)

It's another example of how you have to filter a list like this one. 
The variety of K3 owners is vast, and some push the limits in various 
ways and at those limits, they start seeing things the vast majority of 
us never do or ever will.  They tend to discuss them here, which is 
fine.  Those using the K3 as the IF for transverters up to the microwave 
ranges are very concerned about frequency stability, and often discuss 
it on this list too.  Your K3 will be rock-solid for you on HF, no need 
for apprehension over that either.
