I mean, there are plenty of ways to stop the abuse just using the rules as is.
Standing high jumps are half of your 3+your strength modifier rounded down, which means 7 strength or lower can't do a standing jump,
If the character has a +1 modifier or higher, than a standing high jump is at least 2 ft, the jumping rules don't allow you to jump less than the full amount allowed to you ( since an Athletics check allows you to jump higher, I suppose a check there would allow you to jump lower, but this still gives a chance for failure). Jumping 2 ft means you glide 10 ft. This will activate falling damage of 1d6, which will force the Hazodee to use its reaction if it wants to land on its feet, and you can't jump from a prone position. Also any difficult terrain, including potentially dead bodies, would require an acrobatics check or fall prone, ending the abuse.
