I'm mostly with you here... it's amazing how many devs don't have a certain amount of baseline knowledge to understand file-io, let alone thin abstractions for custom data and indexing like tfa. Then again, most devs also don't understand the impacts of database normalization under load either.

Sorry, this I think is a dangerous attitude: for me it is not about onboarding. Every newcomer reading `Huh, neat` is poised to repeat the mistakes of us and our ancestors.
