nuke medium_eyebrows
deprecate medium_eyebrows
In theory this tag is for eyebrows which are more detailed than mere lines but not quite thick enough to be thick eyebrows, in practice it is ill-defined (post #6759700 post #7668535 post #9793179) and even operating at ideal conditions this seems to be tagging the default.
