Consensus reached during September f2f meeting:
No. However, we should disclose during the application process for EGs what peoples' corporate affiliations are.
EC members should take this into account when voting on JSRs. Diversity is the ideal, but if a JSR is being run in an open and inclusive manner but happens to be "non-diverse" then they may agree that it's appropriate for it to continue.
Separate question: should we publicise the names of the individuals who are representing company <whatever> on the JSR page?
If anyone cares, please open a separate issue.
