Actually I think genomics / bioinformatics is a counterpoint there. One of the things I like about the field is nearly every file format is under-engineered. It's TSV all the way down and if you need compression gzip it. If you need to index that, sort it (literally often with unix sort command) and block-gzip it. Anything more engineered arose specifically because the above failed and something more is actually needed. The downside is it's a giant hellscape of unstructured, poorly specified formats where data types are barely specified at all or if they are most of the schema is published on some rambling blog post by some rando scientist. You will spend most of your time understanding it by empirical reverse engineering of the data that you are trying to deal with.
