act as tiebreakers

if they are acting as tiebreakers, you'll likely want to either ensure that one lead is a tiebreaker, or that there will otherwise always be a way to ensure a decision rather than a stalemate (50/50).

An odd number of leaders could avoid the issue?

I updated the document, only one lead should step up and make the decision.

@Conaclos that wouldn't work. Being a lead is essentially being a core contributor with more burden (conflict resolution rights, holding sensitive info/assets). We can't force people to join only because we require an odd number.

One of the hardest lessons I learned from the io.js Governance Structure that ended up as the Node.js Governance Structure was that the decision to never remove inactive members was perhaps one of the biggest barriers to progress. Eventually, we introduced an emeritus system that IMO has been extremely helpful in distinguishing who is an active contributor vs. who once was but is not longer active.

The Emeritus system also helps ensure a more secure environment, since inactive accounts don't have push permissions, while still allowing for recognition and an easy way to start working again (simply ask to be re-added to the project from emeritus status, and you will be).

To be in good conscience, I feel obligated to at least leave a comment urging you to consider a way to build-in a system to step-down or off-board people who are inactive after having worked in such a system without an escape hatch like Emeritus for so long.

As a non-binary person, I appreciate the last part here, but generally disclosing gender isn't something I'd expect to be done. My guess is that you meant pronouns and used gender as a proxy for that, so here's two suggestions on how to tweak this:

I would strongly recommend keeping these documented in a different place. Governance is usually more of a static document, and parts that are going to be changing with frequency are often better kept elsewhere both to make them easier to change and to allow easier historical parsing of a Governance doc. Going through 50 membership changes to find a specific language change is often less than ideal.
