Sometimes. If you're relying on a toolchain that's parsing and analyzing Python code, things like compilers and mypy will sometimes lag behind new syntax, bytecode and C API changes. Until recently mypy didn't have full support for match statements, and its corresponding compiler, mypyc, still doesn't. Same goes, or went, for full support for match statements in other compilers, as well.
