This is the respective issue for https://www.drupal.org/project/drupal/issues/742344, a blocker for the #5346 backport, and related to #1040.
Problem/Motivation
Accessibility guidelines recommend specific, meaningful error messages when required form elements are empty. However, FAPI currently does not support custom error messages for required elements.
Proposed resolution
Support a
#required_errorproperty for form elements. If set, this message will be used when a required form element is empty, instead of the default "Field x is required." Additionally set a#required_but_emptyflag automatically during validation when the required field is empty. This is an internal property and is not set manually. It allows#element_validatehandlers to set a custom required error message, but without having to re-implement the complex logic to figure out whether the field value is empty.Remaining tasks
Commit feature and document these properties. The feature is a small API improvement that is applicable to both D8 and D7.
User interface changes
None.
API changes
Minor, backwards-compatible addition only. No existing code will be affected. Addition of two FAPI element properties:
#required_error#required_but_empty

I think this is the best gift you can give designers—just design, create a new distribution, and get creative with Backdrop.
Add 'recipe' project type to Backdrop
@yorkshirepudding thank you for the additional info on improving discoverability and a handy way to keep a list of projects for reuse.
Why not add a Github star?
It is a good point @izmeez and when I was researching repo discoverability I found that GitHub search does prioritise matches with more stars. This is what I was researching for:...
