Not sure if being "deployable" is an issue, considering docker exists. So, anything is deployable in the future by default, given a machine running the correct docker image.

Or am I misinterpreting the argument?

Java code will run on the new ARM machines Apple will ship. Running your Docker code in the same environment is not going to be pleasant.

Java already runs on the new ARM machines ;) Someone has OpenJDK building for the server variant, and it works quite well already: https://github.com/gonzalolarralde/jdk/tree/gonzalolarralde/.... Apple had the C0 interpreter up on the day of the announcement because they needed it for various Xcode tools.

I must admit I am completely ignorant to how much of an issue this is in real life, but I'm also in the privileged position of having the backend code compiled and run on remote servers, rarely on my own machine. On the other hand, I'm a junior developer, so I might yet stumble on this problem's relevancy at some point.

To be fair, docker is already a pain on my machine (using Fedora 32). I gave up on using docker at some point.

Apple Silicon dev machines do not currently run Docker at all, or any CPU-level virtualisation.
