As noted in #4490 and D242, the Female class is used to check for female support units and only those.
In particular the Petra bot assumes that.
However it is not inherently obvious that the proper noun Female is different from the common noun female in our case and
so people have confused it and added it to military females in rP19095 or intentionally used it for military females like in the Delenda Est mod for example.
Using precise language not only helps preventing future repetitions of this ambiguity but also allows modders to add a auras, techs or attack bonuses
for all kinds of females without having to use a workaround name.
Removal of female class proposed separately in D242.
