LUCENE-1473 is an incomplete patch that proposes to commit the project 
to new back-compatibility requirements.  Compatibility requirements 
should not be added lightly, but only deliberately, as they have a 
long-term impact on the ability of the project to evolve.  Prior to this 
we've not heard from folks who require cross-version java serialization 
compatibility.  Without more folks asserting this as a need it is hard 
to rationalize adding this.

The process is entirely in public.  You have as much announcement as 
anyone.  Patches are weighed on there merits as they are contributed.

I've already explained the process several times.

We cannot easily make a long-term plan when we do not have the power to 
assign folks.  We can state long-term goals, like flexible indexing, but 
in the end, it won't get done until someone volunteers to write the 
code.  So you're welcome to start a wish list on the wiki, and you're 
welcome to then start contributing patches that implement items on your 
wish list.  If you propose something that folks think is extremely 
useful, but requires an incompatible change, then it could perhaps be 
done in a branch.  But most of the existing community is interested in 
pushing forward incrementally, trying hard to keep most things 
back-compatible.  If that's too frustrating for you, you can fork Lucene 
and build a new community.

Mike does a lot of development, but he also commits a lot of patches 
written by others.

You want Mike to do less?  Others can and do get involved all the time. 
  Look at http://tinyurl.com/5nl78n.  The majority of the things Mike 
works on are instigated by others.

Did you pay Michael?  No one here is compelled to work with anyone else. 
   We work with others when we feel it is in our mutual self interest.
