No.
There are multiple Forms of tests and testers
In game development its not just The playable state that is important. As of The game right now, The shadow build in question, is not playable . It was made to test New mechanics, physics, Graphics implementations, AI behavior, Map stability, and overall consistency of game content.(to check if all flags are being activated and such)
QA testers test The completed project fully to check if The entire project and vision of the Game is working as intended. But as Everybody knows VOTV aint complete yet... So this fallacy of "testers, test the Game by playing" is flat out wrong... Imagine if all testers did that during development of a game?
Imagine The waste of time waiting for all testers to play a game that it has content that needs to be activated by putting hundreds of hours into the game and still missing, for an example, an event?
The game would never get out of development hell
In short... No, This isnt a version to play and enjoy. This version is literally a work In PROGRESS meant to show New ideas, mechanics and etc for The other guys in The team to "spark" creativity and create content.
I agree with The guy above me. These shadow builds should be private because of all The behavior of the community that isnt helping in any way The development of the Game.
Edit: Addendum: You arent forced to play the shadow version. You can choose not to do so. And if the warnings werent enough for you dont forget that Actions have consequences. Be mindful of that
