Is your feature request related to a problem? Please describe.
At the Tor project, we sometimes run large-scale experiments on the network that might affect the performance for some users. It's not an outage or an issue per se, but it's something we want our users to be aware of.

The current "outage" content type is not quite fitting for this.

Describe the solution you'd like
Instead, we have developed an in-house "experiment" content type. That is done with an overriden components.html layout and an extra experiments set of templates.

We'd like to merge this upstream: the components.html diff, in particular, is a problem for us as it's essentially a fork that is quite hard to track.

Describe alternatives you've considered
So far we've kept our changes to ourselves, thinking others might not be interested... But we're finding the cost of keeping the local diff a little high and figured other people might benefit from this as well...

Additional context

Would you be interested in a tentative PR to merge this back in?
