Rule Request: setter functions variable name to value

Please describe what the rule should do: Enforce the variable of the set functions to value.

What category of rule is this? (place an “X” next to just one item)

[x] Enforces code style [ ] Warns about a potential error [ ] Suggests an alternate way of doing something [ ] Other (please specify:)

Provide 2-3 code examples that this rule will warn about:

const person = {
  set name(name) {
    this._name = name;
  }
}

const obj = {
  set shape(shape) {
    this._shape = shape;
  }
}

Should pass with:

const person = {
  set name(value) {
    this._name = value;
  }
}

const obj = {
  set shape(value) {
    this._shape = value;
  }
}

Why should this rule be included in ESLint (instead of a plugin)? I think this would be important to have the same name in all setter functions. I look up for this, but found nothing. value is suggested as it is wide used as the setter variable name, but it is actually not enforced, and could be named anything else.

Thanks for clarifying. Personally, I don’t think this rule would be a good fit for ESLint core, since I think it’s a fairly uncommon preference. However, you could enforce this on your own project using the no-restricted-syntax rule:

{
  "rules": {
    "no-restricted-syntax": [
      "error",
      {
        "selector": ":matches(MethodDefinition, Property)[kind='set'][value.params.0.name!='value']",
        "message": "Setter parameters should be called 'value'."
      }
    ]
  }
}

Could you clarify why you want the argument of all setter functions to be called value? I’m not sure I understand the purpose of doing that; it seems like some setter functions could benefit from more specific names.
