A few thoughts:

People who care about this issue, especially in the last few years, have been leaning into a "memory safe language" vs "non memory safe language" framing. This is because it gets at the root of the issue, which is safe by default vs not safe by default. It tries to avoid pointing fingers at, or giving recommendations for, particular languages, by instead putting the focus on the root cause.

In the specific case of Android, the subject of this post, I'm not aware of attempts to move into other MSLs than those. But I also don't follow Android development generally, but I do follow these posts pretty closely, and I don't remember any of them talking about stuff other than Rust or Kotlin.
