Should `__init__()` be part of a protocol?

protocol_init.py

from dataclasses import dataclass
from typing import Protocol, Type


@dataclass
class Ball:
    x: float
    y: float
    z: float


class Init(Protocol):
    def __init__(self, ball: Ball) -> None:
        ...

    def get_ball(self) -> Ball:
        ...


class BallContainer:
    def __init__(self, ball: Ball) -> None:
        self.ball = ball

    def get_ball(self) -> Ball:
        return self.ball


class TwoBallContainer:
    def __init__(self, ball: Ball, ball2: Ball) -> None:
        self.ball = ball
        self.ball2 = ball2

    def get_ball(self) -> Ball:
        return self.ball

    def get_ball2(self) -> Ball:
        return self.ball2


def make(ball: Ball, container: Type[Init]) -> None:
    c = container(ball)
    print(c)


if __name__ == "__main__":
    make(Ball(x=1, y=2, z=3), BallContainer)
    make(Ball(x=1, y=2, z=3), TwoBallContainer)  # <-- invalid but Mypy allows it
    make(Ball(x=1, y=2, z=3), object)  # <-- Mypy disallows it
