The guy who taught me to kite (a decade or so ago) said that I should always launch unhooked, and if I could not hold the kite's power, then I was on the wrong sized kite, ....and to bring the kite right back into the hands of your helper launcher person.
Those were the days when all inflatable kites were C kites that had very little depower, so we did not ride around super overpowered.
Modern bridled SLE Bows/Deltas etc allow so much depower they tend to promote riding lit as hell and in some cases, more than some can hold when unhooked.
Everyone has gone to a hooked in/depowered launch (it's what is taught now) which can be a problem for those that are unaware of how much power they will be holding at full power.
I had no donkey dick and a loop that did not open for at least the first year I kited (home made bar and line set up), so the chicken loop came off the hook all the time when I did not want it to, but had no release if things went bad.
I had to learn what to do when it slipped off pretty quick....either pull that sucker to the hook or grab the chicken loop with one hand and sheet out with the other, and hook back in.
If you ride with no donkey dick for a month, you will learn to pay attention to your loop.
These days, if you ride hooked all the time, cut the hook off and run a rope strung from left to right on the remaining hook frame base and attach your loop to the rope.
Cuts down on the possibility of your hook contributing to a death loop situation, among several other nice benefits.
