Sigh,
enforced is always top down, sure, if you want to be pedantic. But normally the process starts with enthusiastic devs, propagates out through other devs until a consensus is reached (e.g. source control is the only sane way) and then management starts to enforce it - often with a crappy enterprise take on the basic idea (I'm looking at you IBM Team Connection and Microsoft Visual SourceSafe).
AI seems to have primarily been pushed top-down from management long before any consensus has been reached from the devs on what it's even good for.
This is unusual; I suspect the reason is that (for once) the tech is more suitable for management functions than the dev stuff. Judging from the amount of bulletpointese generation and condensation I've seen lately anyway.
