I think it would be more accurate to say that we voted to move portions of Slider into YARN, and that as we move into this model the Slider PPMC will determine what makes sense to happen with the remaining pieces of Slider. It seems like it's possible the remaining pieces of Slider will become obsolete, and it's also possible Slider could evolve to continue to provide additional functionality on top of what is being done in YARN.
Another thing to be aware of is the concept of graduating to a subproject: http://incubator.apache.org/guides/graduation.html#subproject-or-top-level. What we are proposing sounds kind of like this, except that we are only moving a piece of Slider. (Saying we "have unanimously voted to move Apache Slider into Apache Hadoop YARN. Hence, Apache Slider will not move to TLP" sounds even more like graduating to a subproject.) The Incubator may want a say in this matter, in the form of holding a vote approving the transfer. Since we plan for the Slider PPMC to continue for the time being, this might not be necessary, but I thought I should bring it up so we are prepared for the possibility.
