Who is using Crossplane today in their infrastructure?

We have had incidents where I work of developers or folks new with terraform on the team making manual changes to resources they should not have made, resulting in downtime. I did my own little PoC at https://github.com/autotune/bank-of-anthos/tree/main/aws that implements Crossplane on an EKS cluster, which then builds out its own EKS cluster and resources to support that, and installs a demo provided by Google via helm. What are the cons of this setup? So far I have identified the lack of ability to do a terraform plan beforehand and and the fact that Crossplane is basically brand new on the scene as possible set backs, but the features it offers in exchange for that just seem incredible. What are your experiences or thoughts on it?
