[ig-exploration] Generic decision policy might not be appropriate for the Exploration IG

Decision Policy
This group will seek to make decisions through consensus and due process, per the W3C Process Document (section 5.2.1, Consensus). Typically, an editor or other participant makes an initial proposal, which is then refined in discussion with members of the group and other reviewers, and consensus emerges with little formal voting being required.

However, if a decision is necessary for timely progress and consensus is not achieved after careful consideration of the range of views presented, the Chairs may call for a group vote and record a decision along with any objections.

In previous discussions (don't have link, sorry) there was a suggestion that the usual Consensus process might not be appropriate for a group like this that does research, produces possibly diverse perspectives, and doesn't produce normative documents. Something like

• Gather information, ensuring that both sides of controversial ideas (e.g. blockchain tech, the potential benefits and perils of AI) are considered.
• Seek consensus on matters of fact, and IF POSSIBLE matters of prediction/prescription.
• Do not block on lack of consensus, record alternative positions to the satisfaction of their proponents, and record the rough division of opinion in the IG across those positions.
