BTW, is it just the double question mark? Isn't the single one replaced as well? |

From the code it seems that /(=)\?(?=&|$)|\?\?/See the visualization at: |

| <p>Data to be sent to the server. If the HTTP method is one that cannot have an entity body, such as GET, the <code>data</code> is appended to the URL.</p> | ||
| <p>When <code>data</code> is an object, jQuery generates the data string from the object's key/value pairs unless the <code>processData</code> option is set to <code>false</code>. For example, <code>{ a: "bc", d: "e,f" }</code> is converted to the string <code>"a=bc&d=e%2Cf"</code>. If the value is an array, jQuery serializes multiple values with same key based on the value of the <code>traditional</code> setting (described below). For example, <code>{ a: [1,2] }</code> becomes the string <code>"a%5B%5D=1&a%5B%5D=2"</code> with the default <code>traditional: false</code> setting.</p> | ||
| <p>When <code>data</code> is passed as a string it should <strong>already be encoded</strong> using the correct encoding for <code>contentType</code>, which by default is <code>application/x-www-form-urlencoded</code>. If the string contains a double question mark (<code>??</code>) it is replaced with a value generated by jQuery that is unique for each copy of the library on the page (e.g. <code>jQuery21406515378922229067_1479880736745</code>).</p> |

There was a problem hiding this comment.
We should document it only happens for dataType: "jsonp" or dataType: "json" and the latter will no longer trigger it in jQuery 4.0+.

We also need to take jquery/jquery#4754 into account - in jQuery 4 the logic will only be triggered for requests with |
