WTH, why is there no "yaml action" in the automations/script editor?

If I want to copy an action from one automation to another (like notify-service calls) the easiest way is to grab the YAML snippet, especially since these service calls often include templates that aren’t supported in the GUI. But there’s no straightforward way to enter that copied text into an automation (eg via an empty “yaml action”).

Instead I have to add a random action, switch it to “edit as yaml” mode, and then overwrite it. That should be one step quicker via an action type that directly opens a yaml input!
