Honestly not sure why I didn't do that once the tool had stabilized.

Switched to

    go install filippo.io/torchwood/cmd/age-keylookup@main
    age -r $(age-keylookup [email protected])

age is designed to be composable and very stable, and this shell combination works well enough, so it's unlikely we'll build it straight into age(1).
