With the current speed of mobile internet, there really is no need for a stripped down data saving mobile style anymore(My opinion). However, if a community is using the mobile styles successfully and has a strong user base, switching from the mobile style to responsive can send a shockwave to the regular users who are used to using the mobile style. Change is not always good, even for the better when it comes to a well established forum. I'd recommend any new startup forums to have a well designed and functional responsive style since they will be attracting new younger "social media" types who all pretty much surf the web on mobile devices only, and don't understand how a forum should look or work.
