That really depends I think. Northern systems actually prefers are much wider range of kicks because there are tactical advantages in striking more areas with more tools. If you limit your leg to the lower half of the body, then the opponent can predict that can become more adapted to fighting you by taking mental resources away from defending their upper body from kick and focusing more on their lower half of the body.
About being caught in mid-kick, it is actually rather difficuit (while not impossible) to so. All kicks would be used in conjunction with hand techniques of some form. Only when the hands are kept busy will a kick be launched to the upper body. Hence the 手是兩扇門,全靠腿打人. It is extremely risky to kick someone in isolation with other hand techniques and I have yet to see a single taolu in north or the south that does that.
Modern day practitioners loose balance when kicking because they often make the same mistake. They 'uproot' themselves when kicking and over commit their body into it. The key difference is that most Chinese kicks, evem when they are to the head of chest does not push their hips out as oppose to pulling it back. This allows for the body to stand up straighter and keep the CG of the body relatively firm onto the standing leg. The kicking leg therefore become an independent tool and not connected by force to the body.
Wujiang, it seems everything you've said on how high kicks should be used, from the matches I've seen, really are true. Did you learn this from studying Chinese martial arts? It really seems like there is alot of knowledge that just went out of practice in Chinese fighting.
Here's a video from youtube that pretty much proves your statement about how high kicks should be used
