If they end up using Rome internally that should be a good sign that it will be supported for years to come. React has been very well maintained for the past 5+ years.
I don't know. I don't think they stopped testing, but their open-source javascript testing framework jest has been unmaintained for a little while.
Jest had a new release 5 days ago, so "a little while" is quite literally a very short while.
My bad. It feels unmaintained though.
Isn't this true of all open source projects?
When it's many smaller projects, the workload can be shared and it's easier to replace a dead component.
