Few years ago I experimented with a special opcode for exception matching. It could make the bytecode a tiny bit smaller and faster, but since catching an exception in Python is relatively expensive, it would not have significant performance benefit.

As for splitting COMPARE_OP for comparison, identity and containment tests, all these operations look the same from the compiler side, they correspond the same AST node. Introducing new opcodes will complicate the compiler.
