This is how bash works. Any string with a $ in it will be interpolated unless you double escape it. Also depending on if you use double or single quoted strings.
Spaces as list separator could also fall into this philosophical question of what makes most sense as string separators. Some times it is super convenient, until you have actual spaces in your string and it becomes a pita.
See also the yaml Norway problem for what happens when implicit goes over explicit.
It generates about the same amount of bugs, if not more, and would also end up with a code-review-doctor suggesting you to use /$ over $. In the end, regardless of syntax, a human always have to make the final call on whether interpolation is wanted or not.
