Yeah, I think that's a good point. I'm actually quite on the fence about dynamic and static typing - I like both. With a small team that knows what they're doing, I tend to go dynamic. With a larger team, it does tend to become a bit of a mess and weird workarounds to not having static typing (like some mystical 100% test coverage) start to surface.
I love the approach Python and MyPy took there: Python supports but ignores type annotations. You can add them to any part you want and check it with MyPy, but you can truly do it gradually, and you can always decide not to do it. An approach like that would fit JavaScript beautifully, I think.
