I'm guessing it's just a coin-flip decision.

Hi and welcome to devnet forum

I cannot pretend to know the answer. A quick look showed that xz archive format is single file compression while 7z archives are for multiple files.

BTW this forum is more user oriented. Therefore I doubt that there will be a definite answer from one of the decision makers here. Just out of personal experience Qt installer questions are raised here, but only few responses are given. seldom
