Messages that support GENDER in MediaWiki

Let's stick to actual use cases. Please report whenever you think GENDER should work in a particular use case but does not. Please describe it a clearly as possible. Thanks.

OK, I will. So, here, I need a list of all messages that support GENDER so I can start. It won't help me and the Arabic translation only, but all teams that want to use GENDER. Is that possible?

See documentation.

Great, this was helpful. I noticed that only very few messages support GENDER (according to the docs). In Arabic, any message that contains "user"/"contributor", for example, needs to have GENDER support where possible. Should I report any message here?

Use the gender in your message, and test if it works or not. If it works, document it. If it doesn't work, report it. Thanks.
