If the author would like to take control over its controls, of course that is fair. I suppose also it was a little help to promote the controls through BGRAControls. I suppose that was the intention in the first place.
One need also to take into consideration the users of BGRAControls. What would be the transition for a project using those controls in BGRAControls package? After the controls are removed, is it as simple adding in the projects the dependency to the specific package for uecontrols? As they have the same name, I suppose there is no need to modify the LFM files.
007, what would prevent you from removing the controls? Are there modifications that have been done on those controls? In that case, you could suggest them as patches to ueControls to mrisco.
