1) Doesn't really matter if it was intentional or not, it's like highsticking, you still have to make the call.
Dude, ice is slippery.
Also, trying to hold onto your stick with hockey gloves on is almost impossible. If any of you had ever played hockey, you'd know that FFS.
2) I have been playing hockey for 28 years now and I can honestly say that my stick has almost never left my hand, other than when someone slashes it out of my hand (which hasn't happend much either), I can't even remember a single instance where I lost my stick. I'm sure it's happened several times, but obviously not that often. So, holding on to your stick with hockey glove is actually pretty easy. If you find it almost impossible, maybe you should consider changing your gloves, or maybe the way you tape your stick needs to change.
