Yeah, personally that's the option I would choose too. It should fall on Sass to change whatever they may need to.
It's not completely "kind-of simple" though, as there is, potentially, a fair amount of code written with Sass in currently running projects. It is a cost to consider.
Also, there have been some precedents in the JavaScript community, mainly with Mootools -an old library, mostly irrelevant today but with some existing code still running in the wild- and the name of a couple of methods such as includes and flatten. The thing is that TC39 really pushes for "not breaking anything at all", and by proximity the CSS community seems to have some people with a similar opinion.
