After more than a month of consultation,
feedback and tweaking new font packaging guidelines have been approved
by FESCO.

Package maintainers must now convert their packages in rawhide to the new templates.

The following packages have already been converted in rawhide and can
serve as examples if the templates published in the fontpackages-devel package are not clear enough:

❄ andika-fonts
❄ apanov-heuristica-fonts
❄ bitstream-vera-fonts
❄ charis-fonts
❄ dejavu-fonts
❄ ecolier-court-fonts
❄ edrip-fonts
❄ gfs-ambrosia-fonts
❄ gfs-artemisia-fonts
❄ gfs-baskerville-fonts
❄ gfs-bodoni-classic-fonts
❄ gfs-bodoni-fonts
❄ gfs-complutum-fonts
❄ gfs-didot-classic-fonts
❄ gfs-didot-fonts
❄ gfs-eustace-fonts
❄ gfs-fleischman-fonts
❄ gfs-garaldus-fonts
❄ gfs-gazis-fonts
❄ gfs-jackson-fonts
❄ gfs-neohellenic-fonts
❄ gfs-nicefore-fonts
❄ gfs-olga-fonts
❄ gfs-porson-fonts
❄ gfs-solomos-fonts
❄ gfs-theokritos-fonts
❄ stix-fonts
❄ yanone-kaffeesatz-fonts

FPC and FESCO were not consulted on splitting or renaming packages, nevertheless the new templates make it fare easier to manage subpackages, so you're strongly encouraged to split your packages along font family lines.

A mandatory rule about splitting will probably be submitted for approval before the F11 release.
