Relevant packages and bugs: 943107 git-buildpackage: Python2 removal in sid/bullseye
This bug is not marked as rc.
Nevertheless I believe that this bug report is in-fact a false positive. From what I can tell git-buildpackage, even in buster, does not (build-)depend on python 2 or any python 2 modules. It does build-depend on python-pydoctor, but according to a recently entry in the pydoctor changelog that package "is a Python application and not used as a module" It would make sense to change the build-dependency to pydoctor in the next upload, but it's probablly not worth making an upload just for that change.

Depended on by pydoctor in testing, but not in unstable. Should stop being a problem for git-buildpackage when pydoctor migrates.

Listed as a "blocker" of the above bug but not currently in testing. Personally I advocate ignoring "blockers" that are not in testing, but I'm not sure if consensus has been reached on that.
Bugs which you may notice which are now not so relevant any more because they have been fixed in sid (but not yet migrated): 950216 [git-buildpackage] missing xsltproc autopkg test dependency Fixed in sid; migration blocked by FTBFS due to pydoctor breakage (#949232). When pydoctor has migrated, reattempting build (eg by re-upload) should fix this.
Builds happen in unstable, so there is no need to wait for pydoctor to migrate to testing before retrying the build. I just requested a retry and the package built succesfully. I'd expect it to migrate as soon as dak and britney process the binary.
949232/948831 [pydoctor] needs to depend on cachecontrol 952546 [pydoctor] d/copyright & DFSG issues 937421 [pydoctor] Python2 removal in sid/bullseye
Should hopefully be fixed in a few days when pydoctor migrates to testing, i'm not seeing any obvious blockers for that right now.
