Hi Thiago,

I note that this is a significant change that touches more that just the 
Drag and Drop code, so we will need a broader discussion of your 
proposed enhancement, as we do with any significant change. Go ahead and 
file an Enhancement request so that we have a JBS issue to track this. 
Given where we are in the release cycle and the number of other 
enhancements under review, this is out of scope for JavaFX 13, but could 
be considered for a future release once there is general agreement of 
the approach.

One thing I recommend starting with is a high-level overview of the 
changes. Also, an evaluation of whether (and how) this change might make 
the Glass GTK port easier to maintain going forward would be helpful.
