Yes, I was actually going to suggest proposing this as a general way to address this concern.  Glad to hear it’s already in the works!

As for the proposal, it offers you the ability to retain full control over initialization.  You can even use it in v1 and switch to a manual implementation of initializers in v2 if that is necessary to uphold the existing contract.  Use it when it provides value and avoid it when it doesn’t.
