[csswg-drafts] [css-cascade-7] CSS @sheet - is there a need for an @sheet statement (in addition to block)? (#11998)

KurtCattiSchmidt has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-cascade-7] CSS @sheet - is there a need for an @sheet statement (in addition to block)? ==
CSS layers allow for both statements with rules:

```
@layer foo {
  h1, h2 { color: maroon; background: white;}
}
```

https://www.w3.org/TR/css-cascade-5/#layer-block

...and without:

```
@layer default, theme, components;
```

https://www.w3.org/TR/css-cascade-5/#layer-empty

Does it make sense to follow this convention for `@sheet`? 

My initial take is "no", because `@sheet` only makes sense with both an identifier and a ruleset. If there's no identifier, the rules defined in the sheet can't be applied, and if there's no ruleset, it doesn't have any rules to apply, and thus doesn't do anything.

`@layer` is different, because initial declaration of a layer impacts the cascade order. With `@sheet` identifiers are only used for embedding later, so I don't see any use case for reserving a name for later.
