Villagers run out of supplies quicker on harder difficulties

Currently villagers on bedrock run out of supply for their trades quicker than on Java. The Java system is coming to bedrock, but I think the current, harder system should stay in some way for Bedrock. I think that villagers should run out of supply at different times on different difficulties. Hard mode could give villagers the current bedrock amount of trades, while easy mode could give villagers the Java amount of trades. Normal could give some in between version or have the Java version of it. This would add to the challenge of hard mode, since players will take longer before getting the valuable trades.
