[RandomInteger4]

From what I understand, a lot of that is due to a combination of factors from bugs and spaghetti code from prior to purchase, to the necessity to not change too much too quickly, which might cause a community uproar, to simply just trying to recoup the cost of the IP purchase in the first place by developing projects around the IP, which the main game (java edition) doesn't see any progress from.

Much of the popularity of the game has a lot to do with the modding community as well, which is where you go when simply building in the vanilla game is no longer interesting. Any change to the vanilla game can have major ripple effects on the modding community.

Lastly, I'd say that one huge development they recently fixed in the code base was the block ID limit. Now that the ID system is name based rather than number based with a hard coded limit, the number of blocks that can be added to the game isn't limited by anything other than the direction of the creative team and new mechanics.
