Builds spewing logs of the form "Rule indicated that a canonical reproducible form can be obtained by modifying arguments shallow_since = "...""

I've been using cargo raze for some time in my repo. However, I've noticed that if I clear my cache and build from scratch I get a barrage of errors in the form:

DEBUG: Rule 'raze__ibverbs__0_4_2' indicated that a canonical reproducible form can be obtained by modifying arguments shallow_since = "1615914885 +0000"
DEBUG: Repository raze__ibverbs__0_4_2 instantiated at:

It seems like Cargo raze is not adding an expected field to make the new_git_repository rules be in canonical form. Is cargo raze capable of generating these fields?
