An Argument Against Field Validation
The folks at Prismic explain why they abolished required fields: Unpopular opinion: why required fields lead to terrible UX
Their argument boils down to editor flow, and says that developers should simply account for potentially missing fields in their templating. Developers might have to do this once when setting up a template, but editors would have to deal with required fields every time they generate content.
I might not agree totally, but Prismic argues their point well, and I love that they brought it up and injected it into the common discussion.
