--- Comment #6 from Alexander Ploumistos  ---
I heard back from the maintainers today and apparently there are some Greek
glyphs prepared by the Ghostscript team sometime last year, which are to be
included in TeX Gyre Heros. This has not happened yet, because of an
incompatibility between the two licenses and they are currently working to
resolve that.
