 > * Using `register_setting()` is more appropriate from that concern's
 perspective, however it also has several other side effects. Certainly, we
 should not use the existing `type` field of that function since that is
 heavily used already, and if that suddenly would define what
 `get_option()` returns, that would be a backward compatibility break.

 If we were to use `register_setting()` and reuse the type, there would
 need to be an opt-in. Like a new parameter, like `strict_typing` or
 similar. If a developer opt-in, only then does it force the fixed typing.

 > I tend to disagree. This doesn't sound like a problem. If you can
 remember (copy) the option name, you certainly can remember (copy) the
 type and eventually the default value too :)

 This imply that you are using your own option doesn't it. What if you are
 using a option from a plugin written by another developer. What if that
 developer changes the value from a string to a boolean when updating the
 plugin. No, if we are going to do this, types need to be defined in one
 place. Register settings is the logical place for that.
