Comment:

 When support for multi-use widgets was introduced, a lot of widgets got
 converted from "single" to "multi" at the same time.

 To keep backward compatibility and not break the existing widgets, there
 was some conversion code that would set the "single" widgets instances to
 `*-1` (not sure why not `*-0`, it was a long time ago). In order to not
 overwrite the converted data, the new multi-widgets instances had to start
 form `2`.

 As @tyxla mentions, this doesn't break anything and if changed to `-0`, in
 theory can still overwrite someone's single widgets.
