-## Syntax Alternatives Considered
-
-Some potential alternatives to the `@`-backtick-prefix syntax:
-
-- Triple-backticks syntax:
-  - Pros:
-    - Single-backticks within templates would not need to be escaped.
-  - Cons:
-    - Technically not backwards-compatible. Could break some
-      [real code in the wild](https://github.com/tc39/proposal-string-dedent/issues/8#issuecomment-678731612).
-- Using another character for dedentable templates, e.g. `"""` [#40](https://github.com/tc39/proposal-string-dedent/issues/40)
-  - Pros:
-    - Should be easy to select a character which would be a syntax error
-      currently, so the risk even of very contrived breaking changes could go to
-      near-zero.
-    - Could match existing languages with similar features, e.g. jsonnet.
-    - More intuitive difference from single-backticks.
-  - Cons:
-    - Less intuitive similarities to single-backticks, wouldn't be as obvious
-      that tagged template literals should work or expressions would work.
-- A built-in runtime method along the lines of the `dedent` library, e.g. `String.dedent`:
-  - Pros:
-    - Easier to implement.
-    - No new syntax.
-  - Cons:
-    - Non-zero runtime impact (though less than a JS library).
-    - Open question of whether [isTemplateObject](https://github.com/tc39/proposal-array-is-template-object)
-      would propagate to the output, and [whether this could introduce a
-      security vulnerability](https://github.com/mmkal/proposal-multi-backtick-templates/pull/5#discussion_r441894983).
-    - More verbose.
-    - Couldn't be adopted by ecmascript-compatible data formats like json5
-      and forks aiming at modern es features like
-      [json6](https://github.com/d3x0r/JSON6),
-      [jsox](https://github.com/d3x0r/JSOX),
-      [jsonext](https://github.com/jordanbtucker/jsonext) and
-      [ESON](https://github.com/mmkal/eson)
-
 ## Q&A
 
-### Is this compatible with the [decorators proposal](https://github.com/tc39/proposal-decorators)?
-
-Yes, since decorators require that `@` be the prefix for a valid identifier,
-meaning it cannot precede a backtick/template literal.
