So when engineers left the company, was their knowledge portable? And attracting new talent, did they come with X years knowledge for the custom code? With fewer LOC I'm not sure what you mean, the provider code is pretty small, smaller than custom ansible, salt or puppet modules. Smaller than CDK and Pulumni as well. Sure, you'll have to write Go, but that's about the only hurdle. Everyone doing a round of NIH for internal tooling is ultimately not making the tide rise. Edit: don't get me wrong here, writing internal tools to do a job the right way for the right needs isn't "invalid" or something like that, but people often dismiss the rest of the lifecycle of knowledge and maintenance when making something completely custom.
