I think in my case (and almost everyone else's case) we'll never go Lyft-scale, but with about 100 AWS accounts (and a bunch of Cloudflare, On-Prem [Compute, Networking], GitHub and other providers) and 300 terraform environments we haven't had the problem you described yet.

To us, CI is about integration while Terraform is about reconciliation. Technically both could be categorised as 'jobs', but by that metric, a CD event is also just a job, and so is a migration for an RDBMS and adding and removing products from inventory. But we don't call them jobs, because their specialisation warrants specialised handling. To be fair, we aren't based in the US so perhaps it's more of a localised thing.
