afaiu the only thing that blocks us from moving forward from this task is to provide a way to assign experiment variants to existing accounts with the current GrowthExperiments experiment manager. Per @Urbanecm_WMF's feedback, this should be fairly simple to achieve using wgConditionalUserOptions in the experiment target wikis.

Marking this as blocked until experiment set up is complete (task to be created by Sgs).

@nettrom_WMF, in our last meeting you mentioned you would define treatment and control group more precisely in terms of account ages. For now, we're not restricting any account by its age, all accounts including newly created are distributed 50/50 into control and the treatment group community-updates-module. Is this ok the rollout on Wed, October 30 to Spanish Wikipedia, French Wikipedia, and Egyptian Arabic?

Yes, I said I was going to do that but didn't get around to it, so I very much appreciate the ping on this!

Having thought about this, if we are able to restrict this by account age I would like us to limit group assignment to accounts created after we removed the control groups on Spanish and Arabic Wikipedia. According to T320876#8361765 that would be 2022-11-02. Any account older than that can be kept out of the experiment.

I'm also fine with us skipping this and randomly assigning control and treatment groups to all accounts if you're fine with that.
