Been thinking about this for a bit but am looking for a sanity check / other ideas. I use vals lookups (i.e. ref syntax) with the s3 terraform state backend. I'm going to refactor terraform and clean up the s3 state paths which are pretty gnarly at present, but the vals backend doesn't support multiple s3 object keys or fallback behavior. Similarly if a vals lookup fails it causes templating to fail instead of rendering to null or an empty string (probably a desirable behavior). I'd like to avoid littering my templates values files with lots of conditionals to inform one of two vals lookups (old path and new path). Is there any helmfile and/or vals feature I'm missing that would help me with transition while I'm refactoring terraform state object paths?
