The native version is still experimental and has some issues (https://gitlab.com/packaging/signal-cli/-/issues/3). The java dependencies of the `-jre` version should be no additional problem, since they are readily available in focal / bullseye repos. The difference in the startup time is not very significant, and scli launches signal-cli child process only once anyway, in the `daemon` mode. If a user configures the `-native` version in `update-alternatives`, it should be respected, of course. This ticket is only a suggestion to change `python3-scli`'s install dependencies.
