Link implementation report from spec

[LJWatson]

TPAC will be virtual again this year. There will be a WebApps WG meeting at some point between 24 and 29 October.

There are two things we need you to do in the meantime:

1. Let @marcoscaceres and I know before 17 September if you plan to hold a specification specific meeting (in addition to the general WebApps WG meeting)
2. Post a specification status report before 30 September

Your specification status report should include:

• What progress has your spec made in the last 12 months?
• Is anything blocking your spec from moving to CR?
• If yes, what is your plan to unblock it and do you need any help?
