, I would say jibing is very important to practice....
Yes and no, IMO; I have sailed Sunfish a lot and have a similar lateen rigged dink (a styrofoam Snark that I fiberglassed). With their ultralight booms you can develop some bad habits if you aren't careful. So while I agree jibing is very important, you have to keep in mind that a bigger sail with a heavier boom can do some damage to people and/or rigging if it comes zipping across like you can get away with on the lateen dinks. So experiment to find when accidental jibes happen but remember you can't get away with that on a bigger boat.
