1170209 - [Compat Data] Drop support.support="never" option

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: General, defect)

Description

[John Whitlock [:jwhitlock]]

What feature should be changed? Please provide the URL of the feature if possible.
==================================================================================
The Compat Data API Support resource, status attribute supports a value of "never" [1].  This was to support the use case of {{unimplemented_inline}} KumaScript macro, such as on the CSS @font-face at-rule[2], often used to document that the Firefox developers have decided not to implement a feature.

After a discussion [3], the MDN decided this was better implemented as support.support = "no", with supporting prose and links in support.note.

[1] https://web-platform-compat.readthedocs.org/en/latest/draft/resources.html#supports
[2] https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face#Browser_compatibility
[3] https://groups.google.com/forum/#!topic/mozilla.mdn/zFkqhUji5vA

What problems would this solve?
===============================
No additional display or contribution UI would be needed to distinguish between the "no" and "never" case.  There would not be arguments about the difference between "no" and "never"

Who would use this?
===================
Core compatibility data contributors

What would users see?
=====================
These issues would be marked as no support, with supporting prose and links in the notes, including if the developers have decided to never support a feature

What would users do? What would happen as a result?
===================================================
Most users would get the info they need from the "no", others could dive deeper, read the full discussion, add their $0.02 to the bug, etc.

Is there anything else we should know?
======================================
Code changes:
- Remove "never" from support.support options
- Change handling of {{unimplemented_inline}} in importer
- Migrate data
