No reportIncompatibleMethodOverride on base method with *args and **kwargs

^{Originally posted by **rchl** November 4, 2025}
Not sure if it's a bug, limitation or on purpose so asking here first.

With a code like:

```py
from typing import Any, override

class Base:
def run(self, foo: str, *args: Any, **kwargs: Any) -> None:
pass

class Impl1(Base):
def run(self, foo: int) -> None:
pass

class Impl2(Base):
def run(self) -> None:
pass

class Impl3(Base):
def run(self, foo: str) -> None:
pass
```

pyright doesn't report `reportIncompatibleMethodOverride` in cases `Impl1` and `Impl2`. `mypy` does report:

```
