Last time I did this, we ended up routing our flags through a reloadable config system which used Consul for distribution.

We almost never shared flags across our fairly chunky servicees. We usually found a softer way to do it.

Even with Consul, you can still have enough skew that a few requests in the middle might see A and !A if your request rate is high enough. So it depends on your business model and architecture if that’s acceptable.
