No can do until <app-text/texlive-core-2017-r4 has finally fixed the stupid freetype dependency restriction (or =2017-r4 gets stabilized).

Yeah but =app-text/texlive-core-2017-r3 is still in the tree and depends on <media-libs/freetype-2.9.1-r3 so removal of vulnerable freetype releases would break the tree.
