I know what you mean, but there seems to be some kind of misplace fear about this which has led us down the garden path of unmaintianable config (or even trying to jinja template it!)
If your config is turing complete and consumed as-is, then without a lot of discipline you can dig yourself into a hole, sure.
If you're producing YAML that is not turing complete, that constraint means you have to code in a way that produces deterministic output. It's actually very safe, and YAML maps 1:1 to types in something like Python.
My favourite go-to example is for AWS Cloudformation:

AWS SAM CLI, the command-line tool for building and deploying serverless applications, now supports AWS CloudFormation Language Extensions. The one I am most excited about is Fn::ForEach, which brings dynamic looping to your YAML templates, but it's close. If you, like me, have been copy-pasting resource definitions to infinity, that stops today.
