I'm guessing since both Naruto and Boruto are vessels for Kurama and Momo...the transfer of Karma could not occur for Urashiki (kind of sad).

Also, it theoretically seems eating any form of Chakra-based substance is a Technique created by the Otsutsuki to acquire powers of Karma, without having to die. Noteworthy in that Kaguya's transformation being the most powerful, since she ate the Earth's Chakra fruit....and Urashiki's being the least, since he ate his own Chakra and Eyes. Urashiki literally said that he won't be holding back, so he didn't hold back

Eating one's own body part to gain power makes absolutely no sense.
