Frost Walker II is under-powered

There are two levels of Frost Walker, "I" and "II" (henceforth "1" and "2"). Right now, level 2 seems kind of pointless. Level 1 already has a big enough radius that the player can sprint across an ocean, or ride a pretty fast horse across the ocean. Level 2 is slightly bigger, but has no concrete gameplay benefit that I can tell over level 1. However if level 2 were just a little bigger radius than it is now (possibly one block? dunno how to test), then the player could sprint-jump across an ocean, which would be a considerable boon, allowing for much faster travel (sprint jumping on ice is very fast).

Right now I feel the two enchantments are redundant, and I feel like a minor change to the radius of Frost Walker 2 would make it 'more useful that level 1'. Is there any 'reason'/utility for FW2 to exist as it is? (Another reasonable resolution to this issue would just be to get rid of FW2 altogether.)
