I reported that back in August (thread title was "Verbose license text in a font").
You responded that validators should be aware of that, maybe issue a warning.
Nicholas responded to argue against vagueness in font licensing (which seemed to me unrelated to a choice between embedding and linking to the exact same license) and to argue against a "windows limitation" having any impact on Libre Fonts.
Since I had merely asked for information, had suggested no change, and since I was unaware that preventing Windows users from using Libre fonts was a goal, I let the matter drop.
