In Minecraft Bedrock Edition, stick pistons cannot 'spit out' a block when given a one tick pulse. This alone breaks several redstone builds from aesthetic things such as elevators to effective and useful things like farms. Farms such as sugar cane farms that use 2 way flying machines to collect the harvest are no longer a possibility without some heavy re-work in design along with things such as 3 x 3 piston doors not being able to be as compact as they once were. If the aim for Bedrock is to be completely up to date with Java then please try to make the redstone mechanics the same as Java has. The redstone community takes up a large portion of Minecraft players and Bedrock's broken mechanics sometimes make that aspect of the game seem pointless and unplayable.
