Hi kocur, because the widget title is just a heading element (most likely a <h2>, but that can be theme-dependent) for the Ventus shortcode you just need to add a <h2> element before it to achieve the same effect, so it didn’t feel it was worth adding as an extra parameter.
Hope this helps and explains why I didn’t implement it.
If you have any other questions I’ll be happy to help.
Thanks,
David
