Micro frontends seems like a technology that's similar to Electron in a way. It gets criticised for its performance characteristics but there one can't ignore the problems it tries to solve for medium-large teams — there is a real need for it.

Once webpack 5 adds support for this, I see a lot more folks using it.

Like electron, the performance characteristics would continue to improve in the long term, but may never be as efficient as hand rolling bundles.
