hi Kelly,
It's great to see these changes about to go mainstream. Really appreciate everyones effort in making this happen.  I have a few questions though (apologies if you've already answered them elsewhere) 

1 -  What does 'a limited  time' mean when referring to being able to use the old make file system?  
2 -  Do you plan to actively remove obsolete files?
3-   If so, on what sort of timescale will these files be removed?
