Re: [w3c/webcomponents] The is="" attribute is confusing? Maybe we should encourage only ES6 class-based extension. (#509)

Regarding:
> it wouldn’t be immediately clear by the looking at the tag name that `<my-foo extends="table">` would act as a table

and the problems with handling the attribute (`is`, or `extends`) in some special way, with CE reactions in place

Maybe we could think of just another syntax, like `<table+my-foo>...</table>`, then
```js
element.attributes // []
element.localName // my-foo
element.tagName // table
```
Pros:
- does not require any exception regarding `is` attribute in constructor
- puts `attributeChangedCallback` for `is` out of question
- does not mix concepts of element names and attributes
- it's immediately clear by the looking at the tag name, how it will act

Cons:
- Probably requires parser changes
