A developer is not just a developer. I've been in the industry for quite a while and life for quite a bit longer and I have just never found this sort of pluggability in developers or people in general.

If you want someone to write an etl script from SAP to salesforce you could probably trip over one in the street. But if you want someone to define a well thought out data model in 3rd normal form with versioned entities, property based testing coverage and full CICD pipeline you will have to search hard.
