If you just google for "dlang attributes" you should be able to 
find what you search for, regardless of what it is called, thus 
personally I think greppability is the only thing we have to 
cater for.

If the attribute is in core or truly built-in feels like an 
implementation detail, if nogc was created today, it also 
probably would have been listed in core.attribute. By using a 
different naming convention we actually block refactoring/cleanup 
of the frontend by moving build-in attributes to the 
core.attribute.

However by choosing "use" we could avoid the entire discussion 
about which case to use...
