The bread clip can't come off, it takes a bit of work for me to take it off and I have opposable thumbs. As far as water tipping over, well that won't happen either, but I suppose if someone uses this method it should come with some kind of disclaimer telling the user that they need to make sure the water cannot be tipped over (Good point ). As for it needing to be cleaned due to waste, that's not an issue. The entire enclosure gets cleaned, including the tube.

For me the gain is simple. If the probe is outside then I need to test regularly and adjust my heat often. If my room temperature fluctuates 10 degrees over the course of the day, and my heat tape is set to 100 degrees (as an example), then the temperature inside will also fluctuate... The way I have it, no matter what the temperature it outside the enclosure, it's always the same inside.
