This was completed for 1.0.1 repo. It appears I did not target the v1.1.0 release tag commit as observed by me and reviewing the oscal-cli demo video and looking at oscal-cli --version output, but the penultimate commit. After review with @david-waltermire-nist, this was a tag commit is the merge commit into release/main branches. My analysis is that it is not a major concern at this time, but I wanted to document this in an issue lest it come up. This is done though.
