I think that the highlighted horizontal stroke should be removed.

The right part of the current V glyph has matched the common design of the 豸 component. cf. U+8C79 U+8C7A

There are more than 40 glyphs using the same design in the NomNaTong font. It would be a significant effort to change them all. We would need to better understand the rationale for this design before making such a change.

I still support to keep current form as the Vietnamese conventions.
