organized errors for FieldArrays with composition API

[phislop-sra]

Is there a sensible way to get field-level (rather than form-level) errors from a field array without using vee-validate components? e.g. getting {"users[1].name": ["name is required"]} rather than just {"users": ["name is required"]}

I know it's possible to get that granularity by calling defineField on each field item (e.g. defineField('users[' + idx + '].name')), but I don't know of a non-hacky way to call that in the template, and I don't see how the collection of defined fields would be kept up-to-date with pushes and pops on the fieldArray.

Is there a purely composition-API way of accomplishing this?
