No one else seems to have mentioned this, but POSIX sh does not include this feature.

Until it does, and major POSIX shs have shipped with it for a decade, then the feature will actually exist in a way that the average shell coder cares about. You're better off just shipping Rust/Go/etc binaries and leave sh for your simple glue tasks.

Even I've eventually switched to this, and I've written 10k+ long Bash scripts that followed best practices and passed shellcheck's more paranoid optional tests.

Use the right language for the right job.
