deadcodeonly works with python3.10+ at the moment, because lower Python versions have limited coreastpackage implementation.I see two options, how it would be possible to deal with this issue:
astimplementation from higher Python versions could be extracted and backported to lower versions. But as I see it would require significant effort, sinceastimplementation is tightly coupled with C codedeadcodepackage could implement the missingastfeatures in the lower Python versions. However, this is not a priority untildeadcodefeature set becomes stable.
