There are some QSK systems fast enough to run with a single line if the drive
is delayed by a few ms; the Ameritron QSK5 PIN diode switch in my AL-1200 is
one. But it does have a minimum time between keying and the application of
drive. I think the minimum time is 1 ms, but I'd have to re-read the specs to
be sure. Most transceivers meet that requirement.
The PIN diode switch can also be operated with a keying loop for completely
fail-safe QSK operation.
