Hi Chris!
There is a broader question here of what is the impact of side-channels in MPC. This question was not explored enough in the literature.
Understandably, it is better to make best effort to keep constant time when possible. However, in the specific 3 functions you provided - all of them are verification functions which run on public inputs anyway and therefore not required to be constant time.
