I've just encountered the same problem with fontconfig (after installing 
GuixSD, running guix pull and guix system reconfigure, --no-grafts was 
required).
Would it be possible for the grafts to keep a symlink (somehow registered to be 
part of the grafted fontconfig so that guix gc doesn't remove it) instead of 
patching the binaries?
/gnu/store/<old-hash>-fontconfig-2.11.94 -> 
/gnu/store/<grafted-hash>-fontconfig-2.11.94
