My point (the part that was not simply added information from WPP) is more basic: if one looks at what Tolkien himself published, we find hyphenated Gil-galad translated as Starlight. For myself I would see nothing wrong or inaccurate with the project following this. I realize that over the years Tolkien changed his mind about the etymology of Gil-galad, but I'll put it this way,
if you said: since Celeborn the Teler (from Aman) was the latest idea from Tolkien we must accept this history as accurate... I would also have to disagree.
Since I assume the Silmarillion project is not going to delve into the etymology of the name, or its external history, to my mind 'what Tolkien published' seems a simple enough path to follow. In a sense it's not really about whether 'Starlight' or 'Star of Radiance' is used, but this is a small example of a larger textual issue.
And one that I tend to possibly annoy people about
