I don't mind them not updating this feature... Modders already did it :p (sorry for console players tho....)
I would be interested, however, in a whole new and deeper whims system. The fact that they are addressing it and saying that they would love to revisit it in the future means, imo, that they are THINKING about it but it's not a top priority yet, and it really isn't if you think about it. I'll just patiently wait and use the amazing Bienchen and MissyHissy's mods (can't wait for this mods' updates!!!) in the meantime.
