CF7 Loading state

We have other states such as ‘sent’,’spam’, and ‘invalid’ but not ‘loading’. Instead the ajax loading gif is shown.

To give the user more of a UX I have been adding the loading state to the cf7 scripts.js.

On line 16 on adding this:
$form.addClass('loading');

and on line 89 changing this:
$form.removeClass('invalid spam sent failed');

to this:
$form.removeClass('invalid spam sent failed loading');

My main question is there a better way of doing this/will it ever be added?
