I think it comes down to: Make index.html the starting point, that pulls in the immutable web app, and configures it, (usually with a single endpoint URL that it would typically need). Seams reasonable to me. I'm normally pessimistic about things like this (specifically the 12 factor app which is hopelessly one-sided to specific environments IMHO). But this is actually a useful and captured quite gracefully. It would be nice to see some examples in each of the mentioned frameworks, and hopefully example webpack configuration specifically (since it is often used across all of them).
