Another thing to note is that Mojang had already commissioned a C++ port of Minecraft for the console versions, which they then abandoned in favor of Bedrock. The original console port ran better, was less buggy, and had a nicer UI for controllers than Bedrock. Bedrock is basically an extension of Minecraft Pocket Edition (the smartphone port of Minecraft) so I imagine that they shifted to Bedrock so they didn't have to pay to implement the same features on Java, console, and Pocket Edition whenever they updated the game. The console version was developed by an external contractor, which is probably why they chose to give that up instead of Pocket Edition.
