Address forms: do we need both placeholder values and field labels?

[KFie]

See attachment: the current use of default/placeholder values in input field is incosistent across all address forms on the site. While the majority of fields shows a default values which is equal to the field label, the placeholders are missing for City as well as State/Province. There are also some inconsistencies between spelling of label and placeholder.

Question: do we need both a label and a default value (especially so since we also have #211 which may be removed though)? As the default almost always matches the field label, I find it redundant. When comparing with other stores, I basically come across two ways of dealing with this:

a) Display the label within the field as default; on click, it becomes smaller and moves upwards. Compare with https://www.hugoboss.com/de/registration, for instance.
b) Display the label constantly and do not use default values if the label is self-explanatory. Example: https://dev.kneipp.com/de_de/login/

The issue is not completely fixed in poster v2.1.

Reason--> having a heading for the input and a placeholder seems to be redundant

Placeholder are now everywhere.
