Another problem is the turn-around time. If you
don't give a slight
pause, you might transmit while the other guy's
receiver hasn't
come up.

A "delay" is always required to give a
reasonable bandwidth, as the
envelope rises and falls. Normal rise and fall
is about 5 mS for a
300 Hz BW signal.

After that delay, it takes a period of time for
the receive signal to
recover, whether using QSK or not.

It's always a good idea to force a little delay.
If not, the time you
spend doing repeats (or a busted QSO) can make
up for the 1/4
second or so you don't pause.
