I wouldn't do this via inheritance like this.  You expose this inheritance to
the web this way.  Instead I would just have two copies of the IDL, one with
each interface.

Exactly, what Eric said:
IDLs are *public*, so they should accord to standards.
Implementation details should be either in:
* (Blink-specific) Extended attributes
* Blink C++ code
In this case, using [ImplementedAs] on the interface seems best.

That is, the C++ class should be Gamepad (= public IDL name),
and we can have the legacy IDL interface as:
[
    ImplementedAs=Gamepad,
] interface WebKitGamepad {
    ...
};
