It sounds a good idea. It'd be nice to be documented in the web site for new contributors.

Do we need another WPT-exemption-reason 'non-standards' for WebKit specific features?

I think WPT-exemption-reason should be in the test case rather than ChangeLog.
It's easy to know what WPT-exemption-reason is the file you are watching.
It's easy to know how many WPT-exemption-reason:urgency test cases are remaining by grepping.

In addition:

WPT-PR: https://github.com/web-platform-tests/wpt/pulls/XX must be present in LayoutTests/imported/w3c/Changelog, this is to ensure tests are not lost at the next import.

Who will do the next import? Will someone update all test cases linked by the WPT-PR line after the test case is committed to WPT repo? Or, will someone update all test cases periodically?
