It would make for more work in curved sections of a frame, but it looks to me like it would result in a very rigid structure.
i had an s10 that i welded the frame diagonally behind where the boxed part of the frame ends. if you look at my photos you will see where i totaled it and because i had done that i saved my motor and trans and trans crossmember including surviving with minor injuries. i think that if i had just boxed the frame it would have caved in more on impact. every s10 i build now gets that upgrade.
