You raise an interesting and important governance question about the size of ZCG.
I shared a few broader thoughts on governance here: Anaximander for ZCG (December 2025) - #3 by Anaximander
On the specific question of committee size, I can share some direct experience.
I have sat on committees of all sizes, from small technical groups to large international committees (20–40 or more people) in the context of the Financial Stability Board. Some large ones ran very smoothly, some small ones less so. The decisive factors were not the raw number of seats, but the expertise of the members, the clarity of roles, the stakes involved and how well the discussion was organized when needed.
Seven people is still a small committee. Responsibilities can easily be shared organically and the discussion kept efficient without any formal chairing structure.
The real questions are simply:
• Is there enough work and enough diversity of tasks to justify two more members?
• Would two additional high-calibre people bring more value to the ecosystem than the extra cost (including extra coordination) ?
I don’t have the inside view yet to share an opinion.
Happy to discuss further.
