I've been going through a lot of historical biographies lately and am surprised to see how often archaic gendered terms such as poetess, sculptress, and aviatrix crop up in Wikipedia articles. I know some of these come from the older sources such as the 1911 Britannica, but in other cases their inclusion is the result of decisions being made by editors. There's currently a discussion on [[Talk:Amy Johnson]] over whether she should be referred to as an aviatrix, for instance.
I'm wondering how this has been dealt with previously and if there are specific policies surrounding such uses. I've found the essays [[Wikipedia:Gender-neutral language]] and [[Wikipedia:Use modern language]] and note that [[WP:MOS]] says "use gender-neutral language where this can be done with clarity and precision". It seems as if despite these fairly clear precepts, the use of these terms persists.
Are there any archaic terms where it has been broadly agreed that using them is not encyclopedic? I would be much obliged if anyone could point me to previous discussions about this.
