What is the request?.
I want to be able to access the keyboard layout from the lang array in the LanguageWidget.

Why is it useful?
Some people use different layouts with the same language, like this:

In those cases the current options returned on the lang array, are not enough to see what the current layout is. For example, in the image shown, the language component would only show e.g. en-GB in both of those cases, even though en-SE and en-US would give better info that what kind of layout the user currently is writing in.

How could it be implemented?
The current objects stored in the lang array contains

{
  'language_code': language_code,
  'country_code': country_code,
  'full_name': full_name,
  'native_country_name': native_country_name.value,
  'native_lang_name': native_lang_name.value
}

and that could be extended with keyboard_layout which would return the current layout like se-SV or just SV, en-US, US or some other identifier.
