Besides, regarding comparison with Sasuke's CS, it's a quite different case than the situation with Boruto's mark. Back in part 1, all the higher-ups clearly knew what they were dealing with - I mean, Oro left the same mark on Anko earlier, there must've been enough time to study it, especially since Hiruzen managed to supress it at some point. And even Oro himself bluntly told Anko about his reason of planting CS on Sasuke (that he's going to make Sasuke his future host). In Boruto's case, neither the true nature of the mark (if it's a CS or something else) nor Momoshiki's motives of giving it are known.
