I don=E2=80=99t have a clear opinion on =E2=80=98font-awesome=E2=80=99 yet,=
 but I have some
comments: (1) only some of our font packages are built from source
(though I think we should do more of that), (2) the font might be
considered =E2=80=9Cnon-functional data=E2=80=9D rather than software under=
 the FSDG,
and (3) the font is a =E2=80=9Cfree font=E2=80=9D under a license (SIL OFL)=
 that doesn=E2=80=99t
have a clear notion of corresponding source like GPLv3 has.
