It has NOT been changed, though I too would like it to be. Along with the addition of linking pics/docs to the estimate, followed by the work order....

I only have one major concern with the Estimates module using
it's own BOM and Routing.  We use the Estimate module extensively for  
standard product pricing.  If this module can ONLY use it's own BOM and Routings,
then we will have duplicate data that we would need to try
and keep in sync (Like AR-A and CM-A).
 
When we want to use it to price a modification of a standard product, we just copy
the standard product BOM and Routing to another Item #
(kind of a pro-forma BOM and Routing), make modifications to it,
and then use the Estimater on this new item #.
