That being said, I no longer have any clue what features exist in Google's ecosystem because their A/B and feature flag rollout system is so fundamentally broken and misused by the product teams that some features literally never arrive for some users until they factory reset their devices, and suddenly they get a fresh set of feature flags. I am still waiting on just about all of the new RCS features Google announced months ago, and just yesterday I spent a bunch of time trying to figure out why my partner's devices never received cross device timers while all of my devices do. That feature was launched in May of last year. My partner does a lot of the cooking, and our kitchen Nest Hub usually handles the timers. But only my phone and tablet receive it's timer status...

I say misused above, because it strongly appears that they announce features before completion and then use an extremely shallow rollout to finish the features with the cover of "finding bugs". Is it actually released if the only Google accounts that receive the flags are the dev and product team members?

Google, you've perverted a fantastic engineering practice into a broken mess that reduces your user's confidence in your product and breeds confusion that hurts your brand.
