Beats "none" most of the time that I see people calling CQ on HF.  You gotta
keep calling for someone to hear ya...

My experience with HF mobile is that it is more typically used by travelers
on long trips when they have the time to tune around, call CQ or make
contacts, or whatever.  It wouldn't make any sense to send CQ if one was not
going to be there a while...  OH,... I see your point.  Yes, I should have
said "everytime you will be operating HF mobile"...

And of course, it would make sense to include some time limit, if it is not
going to be a long period.

Again, CQSRVR is instantaneous.  If the others are not listening, at the
instant, then it is like any other CQ, it doesn't exist.  SO there is no
"lingering" CQ just hanging there.
