When will they add keyboard and mouse support for Console players for r6 siege ?

I have a PC and PS5, but my PC is being used by my brother for work most of the time, which then makes me hop into ps5. I'm pretty good with controller but it icks me and spoils the fun out of it sometimes. Since they have introduced crossplay, why cant they add MnK support for consoles ? I'm fine with lobbying with PC only. It just does not makes sense, not adding MnK support while enabling crossplay
