The proposal includes a lot of things, but it's so far just a proposal. 
  There's been no vote to formally define what 1.0 will mean.  In every 
discussion I've heard, from the very beginning of the project, it 
primarily meant API stability.  You've added wire compatibility, data 
stability, security, restart recovery, etc.  These are all very nice 
features to have, essential perhaps in some contexts, but they may nor 
may not be required for 1.0.  I worry that if we keep piling more things 
on, we'll never get to 1.0.

What would be wrong with calling it 1.0 when we have end-user API 
stability?  Why would that be a bad thing?
