Hello antanana,
Thank you for the updates.
I think that the changes that you outlined are good to consider.
I must point out that, at this time, the WMF Board has not received consent from the community to make changes to its size or composition, nor to alter the terms for the holders of community-nominated seats to the Board.
I suggest that the Board start an RfC on Meta regarding extending the terms of existing community-selected trustees by one year. This would be a simple RfC and easy to implement.
A more complex RfC would be needed regarding the size and composition of the Board. Perhaps the staff time and money that are being spent on the brand project could be redirected to supporting this discussion.
WMF has a pattern of making significant decisions which it has not discussed with the community in advance and for which it has not obtained the community's consent. The fact that the Board continues in this pattern even after a governance review is concerning. I hope that the Board will consider how to make further improvements in this regard.
