Add a setting to make stripping #required values from customer profile fields in its reference widget optional

I notice on the admin order ui form, required customer profile fields are no longer required?

I was able to validate the fields manually as required using a form_alter hook, however, even though the profile failed validation, the profile was already saved, e.g with a required field empty.

Further investigation shows in

commerce_customer.module line 1020
commerce_customer_profile_manager_validate

The profile is actually saved during validation

There's a "TODO, trap it on error, rebuild the form with error messages" but that looks like it's not implemented yet.

Is there any way to validate customer profile fields on the order ui form without saving the erroneous profile?

Alternatively, I may need to do js-only validation...

Thanks in advance, and thanks again for the great module set.
