My request was to add more value to LR through adding other feature that are not part of ACR.
This a "relative" issue. Adding extra functionality outside of the Develop module in Lr isn't an issue. Since ACR
is the Develop module, you are going to have a severe uphill battle lobbying for features to appear in Lr/Develop module that are not in ACR. Not necessarily for a lack of support for such an idea ... but that Mr. Noll or the ACR team would be unlikely to provide such, because as mentioned earlier, it is ACR development that is then ported/rewrapped in a different UI for Lightroom. ACR and the Develop module are not really separate entities in the truest sense. They are exactly the same toolset in a different visual presentation. Identical twins with a different fashion sense, if you will ... splitting up this family is not going to be open for discussion, nor is it likely a sensible option at this point in time.
I find it curious why one would want to add features to Lr, yet not desire to see those features in ACR. From a purely functionality aspect of course. I don't see how having identical capabilities for RAW development in ACR
and the Lr Develop module would be a problem.
