Lava and water aquifers changes from Java 21w43a aren't brought over to Bedrock

The latest 21w43a snapshot made some changes to lava and water aquifers, as the following:

• Aquifer water levels change less often, so you’ll more often have larger areas with the same water level. This means slightly fewer underground waterfalls and slightly easier underground boat travel.
• Lava aquifers are slightly less common.

However, on Bedrock, these changes are yet to be seen. This can be compared between the seed and the coords down here, with the following screenshot down below:
