Who cares though? Sealing the battery in makes the device less drop resistant. I somehow managed to avoid water damage to my phones for decades, while none of my phones managed to avoid being dropped in a way that would most likely be fatal to them if their batteries were sealed in - and yet most of them survived to this day.
A phone needs to handle some rain droplets falling on its screen, anything more than that is a gimmick that's not worth the downsides it comes with.
