+Subject: [PATCH] Drop cpython-freethreading from the cibuildwheel enable
+ groups
+
+cibuildwheel 3.0 removed the cpython-freethreading enable group -
+free-threaded builds are selected by the build identifier itself now,
+not an opt-in group - and its config parser rejects the value outright,
+before any container starts and for every interpreter in the matrix:
+
+  Failed to parse enable group. Unknown enable group:
+  cpython-freethreading. Valid group names are: cpython-prerelease,
+  graalpy, pypy, pypy-eol, pyodide-eol, pyodide-prerelease
+
+Upstream's build_wheels.yml pins pypa/cibuildwheel@v2.23.3, where the
+group is still valid and is what enables its cp313t wheels, so dropping
+it upstream would lose those wheels there.
+
+Upstream-Status: Inappropriate [needed only for cibuildwheel 3.0+, which python-wheels pins repo-wide; upstream pins v2.23.3]
