I understand your point of view but I also understand the need to wait untill the stable version comes out. When 2.8 became beta, we were told that that meant: polishing the existing tools and no more adding tools. Just making the soft stable for it’s release.
Yet, since then, there has been several major changes like keybord shortcuts changes, new tools added, UI modifications…
All those things are really annoying for any tutorial maker because any tutorial made before one of those changes makes the video obsolete. Therefore it’s safer to wait untill the stable release comes out. Moreover, lots of people are still using 2.79.
As much as I’m looking forward to seeing 2.8 tutorials I understand the choice of waiting for the official release.
