I was surprised to see the IPMC Flume graduation VOTE today -- I don't recall
seeing another situation like it in the last couple years, where the community
graduation VOTE was contended.

I checked the Flume dev list archives and I don't see a message from Ralph
indicating that he thinks the latest measures address the concerns that have
been raised.

Last September, Jukka wrote this on the ManifoldCF dev list:

    To put things in perspective, since the beginning of this year Karl
    has made over 96% of all ManifoldCF commits. This makes the bus factor
    [1] of the project pretty high, and suggests that a more diverse
    development community is needed. The solution is not to have Karl
    commit less, but to get other people to more actively join the fun.

    The situation here is roughly similar to what we experienced during
    the incubation of Apache Tika. In the last year before graduation
    (2008) I was responsible for about 87% of all commits, which raised
    similar concerns about diversity [2]. The solution then was to
    graduate into a Lucene subproject instead of a full TLP, so that the
    larger project could still provide oversight and continuity in case
    things went wrong.

    Since then Lucene has shed out most subprojects to avoid being too
    large to manage, and by the time Tika in 2010 became a TLP by itself
    my share of all commits had shrunk to a still high but much more
    reasonable 62%. Today I'm still the most active committer, but my
    share of all the activity is down to 44%.

What are the percentages we'd like to see with Flume?
