> ! is the logical not operator
CSS doesn't have a logical not operator
> Add an alias for !important
At this point it doesn't seem feasible to deprecate `!important`, so adding an alias will just increase confusion IMO.
> *important
That's problematic, because that's valid in a [`<declaration-value>`](https://drafts.csswg.org/css-syntax-3/#typedef-declaration-value). But a top-level `!` is not, so it can act as a delimiter.
In particular, this would break:
```js
document.body.style.cssText = "--foo: bar*important";
document.body.style.getPropertyValue("--foo"); // "bar*important"
```
