players can no longer go into the best swimming (gameplay) animation

Players used to have the ability to go into a [gameplay] swimming animation when they instantly touch the deep and shallow waters of Minecraft. People like ibxtoycat (who has mentioned it in his Youtube series), Megan Miller who wrote it down in her book tited: The Ultimate Unofficial Encyclopedia for Minecrafters Aquatic, and some of the people on the Minecraft feedback website noticed the swimming animation as well. which they enjoyed using very very much. But for some reason it was removed and it’s been making things more difficult for players to be able to swim, and have fun with it, in Minecraft itself. And we are only left with these features that aren't event fun at all:

Java (computer) Players do have the ability to go back to features like these; but there are some people that don’t even own a computer. which don’t make any of this fair for them, cause they can’t be able to go back to these features once their Minecraft bedrock version have been updated.
SO what I’m asking you Mojang studio, is for you to please give back these features back to the public. And for you to give us a way for us bedrock player to be able to downgrade our Minecraft bedrock platforms, just like the java Minecraft computer players can do.
