What you're proposing alters the semantics of JavaScript-the-language, which is outside the scope of the Deno project. Pretty much everyone is already in the habit of avoiding variables in the global scope. Why should they go to the trouble of redefining the semantics of JavaScript for something that is already widely understood?

`Deno.cron` isn't JavaScript-the-language. It is part of a runtime. They could implement this in a different way. Just like how Web Workers still just use JavaScrip-the-language, but within a different execution context than `<script>`.
