Alternatives to making this change and other considerations.

The process ❗

The process for changing the governance pages is as follows:

• Open a pull request in draft state. This triggers a discussion and iteration phase
  for your proposed changes.
• When you believe enough discussion has happened,
  move the pull request to an active state. This triggers a vote.
• During the voting phase, no substantive changes may be made to the pull request.
• The Executive Council and Software Steering Council will vote, and at the end of voting the pull request is merged or closed.

The discussion phase is meant to gather input and multiple perspectives from the community.
Make sure that the community has had an opportunity to weigh in on
the change before calling a vote. A good rule of thumb is to ask several Council
members if they believe that it is time for a vote, and to let at least one person review
the pull request for structural quality and typos.

I believe this is just a wording alignment and does not represent a shift in actual governance, and hence does not need a full vote.
