We should add the MirahezeMagic ReCaptchaNoCaptcha (ReCaptcha V3) to TranslateWiki. This is just so we don't forget. We need to do upstream patches for this ourselves, or create an upstream task to request this.
This is somewhat important to do as well as it is what localises errors. Otherwise users that don't speak English will have no idea what to do, or why something like login is failing for them should they be a real user. The messages currently say to contact us in that event which should likely be localised. If I'm the only one who thinks that this is necessary feel free to close this though.
