Regression in phone number Drupal views integration

This regression was introduced in CRM-19274

Prior to 4.7.14 it was possible to list several phone numbers for a contact in Drupal Views using four fields, such as:

CiviCRM Phone Details: Phone (Home)
CiviCRM Phone Details: Phone (Home mobile)
CiviCRM Phone Details: Phone (Work)
CiviCRM Phone Details: Phone (Work mobile)

Each field would be set up to only show a certain combination of Location Type and Phone Type, eg:

Since upgrading the SQL has changed and this only displays one phone number, multiple times. The phone table is not being joined multiple times. So the output is:

Home: 0333 333
Home mobile: 0333 333
...

It is now required to add a relationship to the 'Phone detail' and then add this relationship to each phone field, eg:

(Related Phone) CiviCRM Phone Details: Phone (Home)
(Related Phone) CiviCRM Phone Details: Phone (Home mobile)
(Related Phone) CiviCRM Phone Details: Phone (Work)
(Related Phone) CiviCRM Phone Details: Phone (Work mobile)

This displays the different phone numbers correctly:

Home: 01111 111 111
Home mobile: 02222 222
...

If we are now required to create a relationship in order to use the Phone detail: phone field correctly, then it should not be possible to add these fields to the view without the relationship being defined.

I consider this a regression because it has altered functionality, and necessitated a change to any Drupal Views that list phone numbers from CiviCRM.
