It's a trap. You only need to find the happy medium if you accept the constraints that generate the trade-off in the first place. And in at least three of the four antagonisms you list, it comes down to the DX of the tooling. Static typing isn't so much of a pain if your type errors are helpful and descriptive. The missing brace in the XHTML doc is easily found when using proper and easy to use XML linters. And I don't see why writing native apps shouldn't be as simple as writing web apps. At least there are attempts that seem to get some mileage out of the idea (e.g. Revery, Flutter). The trick is to make the toolset more approachable.
