If I open a function and click the + to add an implementation, the default will be composition and not code, and the Publish button will be grayed out.

If I change from composition to code, the code field will be an empty textarea (with syntax highlighting), the language field will be an empty dropdown, and the Publish button will be grayed out. So far, so good.

If I select "javascript" or "python" as the programming language in the dropdown, short boilerplate code will be inserted into the textarea, and the Publish button will become clickable.

Is it by design? It would make more sense to me to make it clickable only after I change the boilerplate. Is there ever a reason to publish the boilerplate that doesn't do anything?

Another small corollary is that if select a specific programming language from the dropdown, but then change back to composition, the publish button stays clickable, but if I actually try to click, the user interface complains that I didn't fill the function for the composition. I guess that it's not harmful, but it would make more sense to me if the Publish button went back to grayed out.
