As noted by fatherbushido in http://trac.wildfiregames.com/ticket/4490#comment:17 #4490,
rP19095 added the Female class tag to the briton heroine Boudica, while the tag is intended to only be used for support females and
the petra bot has checks for that class, so coming on and removing that separately.
To prevent template editors from repeating this mistake and to allow modders to add technologies, auras or bonuses that apply to all females (including military females),
using precise language and renaming this class from Female to SupportFemale is preferable, but independent of this removal.
The Chariot class for the same unit was introduced in rP10804 and now seems unused, but cleaning that is not part of the scope of this proposal and
perhaps it might be kept if modders want to add that attack bonus or a tech for chariots.
