Maybe the kerning functions are not implemented yet?
It seems so, yes.
The LuaHarfBuzz projects list the full api and there are many kerning related functions: https://github.com/ufyTeX/luaharfbuzz/blob/abe15fef9f2bbf9e68bc54c7057056bcd73032bb/status/full_api.txt In the file `done.txt` there are no kerning related function. https://github.com/ufyTeX/luaharfbuzz/blob/abe15fef9f2bbf9e68bc54c7057056bcd73032bb/status/done.txt
Thank you for pointing to this repository. I will open an issue there, even if the last update of done.txt is eight years old.
