test: Remove vulture from ci, Remove some --min-confidence=60 unused code

maflcko commented at 12:34 pm on March 12, 2026: member

Currently, vulture is run with --min-confidence=100, which reduces its checks to dead code after control statements, which is nice, but not really a common nor severe issue. See the discussion in #34810 (comment) and commit 5c005363a880c136cc44ff2456a402e398fcbf44, which had to remove dead code manually.

Reducing the confidence has shown to be too brittle/tedious in the past, so remove the tool for now from CI.

Of course, removing this from CI does not prevent anyone from running it locally and removing dead code.

Went ahead and did this myself. I ran vulture $( git ls-files -- '*.py' ) and then manually went through the ~200 lines and removed the stuff that was really unused.
