Yeh that is fair enough if you are catering to kids as well then that changes it somewhat. You do need to be connected to the internet for the moment. The YouTube jailbreak is the one that has been optimised to around a second. I use that same one but an older version that takes around 10 seconds but hasnt failed once yet.
There is a new blueray based jailbreak that has been announced and is working just no super reliable at the moment. This just requires a blueray disc to be burnt with a payload on it, so when that matures I'm sure there will be a reliable, without internet way of doing it.
With the speed everything is progressing I'm hoping that before long there will be something that can be done to just permanently enact these changes but for the trade offs, for me, it is worth that little extra time each boot.
Having been on a 1660ti for the longest times just exploring the ps4 and 5 catalogue has given me lots to play before I start trying to load steam games on mine :D
