I need some custom attributes. data-test-id or id or name for e2e tests, and autocomplete to let browsers properly fill out login/signup forms.

I've been using Form.View.custom so far, with CustomConfig and it works out for styling (bootstrap in my case). However, TextFieldConfig etc have only label and placeholder hardcoded into their attributes.

I am kind of lost here. Did I completely miss something?
Is this simply not possible without a PR?
Or should I start by copypasting the whole of Form.View.custom and everything "under it"?
