The thing I really respected about FB product orgs generally was that really did ship things quickly

That's funny about your last line about Messenger. When I was at Facebook in 2020 and 2021 I thought the "Lightspeed" version of Messenger [1] was something of an engineering marvel. Specically the way it was centered around SQLite as the datastore, how the sever side could integrate with it, and how the UI was power by this reactive-style framework written in C. With lots of testing to keep binary size under control and things working reliably. And the DX was not bad for all these constraints.

There were other reasonably nicely engineered things there, like some of the code-as-configuration things in PHP like the ORM and the structured logging.
