Ha ha it's funny because this growing over a few hundred milliseconds is actually already in the game, although it's not very noticeable. :) I did it more as a polish thing though. As a design decision I do want all blocks to have the same size for consistency and do a check if a block can spawn at that location because of this. I could be a good idea to make the checking area a tiny bit smaller than the keys to make the spawning easier and make it require less precision, but I will have to test this.
