That is correct.

The issue that prompted this change was in effect created by the number of
committers in different mature projects (aka, the fact that XAPI has 12 -
14 - I have to verify the correct number, as some people in the XAPI
committer list don't work on XAPI any more). Where according to the
current scheme, projects with large leadership teams can in effect use
their larger voting block to get their opinion through.

One way of maybe addressing this, would be to be more specific about the
minimum size of a Leadership team (see "Projects without functional
Project Leadership Team"). I think a team needs to have at least 3 members
to be functional. Another way to add an extra check may be to add a
specific requirement to Graduation Review which checks that the Leadership
team is of an appropriate size for the size of the project (although we
may have to be specific on what an appropriate size is).

In reality, we don't have a problem with this today, as the leadership
teams for the two mature projects (XAPI and Hypervisor) are actually
large. We have
* 7 for the Hypervisor
* 12 for XAPI (although this is probably to big, but in reality
participation tends to be low)

The two projects which could qualify for maturity in the coming year are
Win PV drivers (3 leadership team members) and MirageOS (probably should
have a similar size to the Hypervisor Team).

Also, it is worthwhile pointing out, that Global Decisions should
practically hardly ever be needed. Only in the following situations
1) Creating, graduating, completing/archiving of sub-projects
2) Some changes to this document (goals, principles, project wide decision
making and project governance): if we apply the new rules, only this
change would need a global decision (as we added a principle and changed
local decision making). And this would be the first one, we had since
introducing the governance 5 years ago
3) Namespace issues: aka naming conventions for lists, ... - which
primarily would be bike-shed issues. But again we only used this once
4) Boundary issues: aka making local per-subproject policies and
conventions global

The only other way I can think of is to weight a project's vote by some
level of activity (e.g. proportion of contributions averaged over 3
years). But that would become complicated.

Another way may be to add an extra bucket which contains all projects. In
the example above

project A, leadership team size 2, total positive votes 2, 100% (pass)
project B, leadership team size 12, negative votes 8, positive votes 4,
33% (fail)
ALL (which is like the popular vote): size 14, negative votes 8, positive
votes 6, 42% (fail)
Average 58% (or very close to) -> fail  ... which does change this example


Or some sort of rule, which requires that the popular and aggregated votes
have to be within a certain percentage of each other, otherwise the vote
does not count and has to be repeated

Please do
