Not a TWN issue; help is welcome to go explain the importance of gender support to every software project out there.
It seems people for years are waiting on this thing, FWIW, there's a number of requests about it, so I'm wondering what's the problem here
What exactly are non-MediaWiki messages?
MediaWiki is among the few progressive software projects that actually is capable of supporting GENDER. We can vouch this for other projects as well, but in the end it is not possible for us(me?) to go and do it for (each of) them.
