I feel a need to intervene here. Moodle is first and foremost English oriented and as such it has some blind spots here and there.
For example, the whole RTL issue. Even in the code, the "left" class will float the element to the right on an RTL site, and a more current example, until a recent fix, when using a keyboard to move inside the navigation block, you needed to remember to press the RIGHT arrow key in order to open a branch.
Another example is the language. The English language is gender-less in many aspects, but there are plenty other languages out there that are more gender specific. Since we can't all be Sweden (look up "hen") some adjustments are needed to be made in order to avoid a `single gender` approach.
A gender field can make a difference even only on the interface level, where a female user will receive a site that display data to her, and not to a `male` her.
It's the little things etc.
