Not convinced that this offers a significant advantage. The component 
writer has to consider so many differences to Delphi anyway, so I would 
not care about a different icon naming convention. I am against 
deprecating the old naming scheme because we would have to rename 
thousands of icons (and their svg source files).

Rather than that, I think the effort should be put into support of svg
