It's observable, e.g. Firefox is already using parse aliases for prefixed system colors:
```html
<!DOCTYPE html>
<script>
var { style } = document.documentElement;
style.color = "-moz-field";
document.write(style.color + "<br>"); // "field" (parse alias)
style.color = "ActiveBorder";
document.write(style.color + "<br>"); // Currently: "activeborder" (not an alias)
// Proposed: "buttonborder" (parse alias)
style.color = "";
</script>
```
