There was a problem hiding this comment.
This doesn't typically matter in a verification context, unless you want whole algorithm to be constant-time for some reason (I know there are some cases of "unusual requirements" for that)
FWIW I hope in the next release we can switch to using wNAF for verification which will be variable-time but faster. The ecdsa crate already makes use of variable-time inversions.
