v3.3.0 is breaking create-react-app's custom webpackHotDevClient

[cvle]

create-react-app and ejected projects use a custom webpackHotDevClient. This PR #1738 prevent those users from being able to upgrade to 3.3.0 because the default client is always injected.

Another related issue is that I am also using the Node API to have better control where to add the inline entries and where not to. For example I only have HMR enabled inside an iframe and it works great, but 3.3.0 is breaking my HMR setup.

Can we maybe hide the automatic injection of the inline entires behind a flag or the other way around, prevent the automatic injection using a flag?

Why issue template was ignored, it is really difficult to do this?
