Yes, what we thought and already reported that to Avi.
Thanks for the answer. We still hope that Avi will change his idea in the next days, because we already know that if one dev removes / downgrades things then 1000 other need to fix such things.
How much complex is this to fix we have no idea, reason why we asked. Ideally the best way to solve such problems is to look where the issues are starting, in such case with the main dev.
PS: don't forget at least to implement this

Avoid auto update of the app too. So don't install new incompatible app automatically, which make no sense at all."
