These own GPU objects, memory or refcounts in their destructors (or assert there that they were torn down), so a copy would double-free. Nothing copies them today; this keeps it that way. The manager base classes cover every backend's subclass. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
