I am surprised it uses macOS as the demo, as I thought it would be harder to control vs Ubuntu. But maybe at the same time, macOS is the most predictable/reliable desktop environment? I noticed that they use virtual environment for the demo, curious how do they build that along with docker, is that leveraging the latest virtualization framework from Apple?
I think Microfrontends could really work pretty well if you have end to end vertical tooling support, like organization unified package management, authentication, logging, error tracking, testing, CI/CD etc. If any team can bootstrap all of these vertically supporting any major frameworks, then it might be a good idea. But let's face it, most of us don't have that luxury.
