If I recall correctly, MUDs basically were kind of the precursor to MMO-style games. Or at least RP in MMO-style games. As such, I don't think SE would even consider a "backward" step like that, especially for such a small niche group of its player base. Sure, they provided the RP tag and lore material, but developing a whole extra (if outdated) game specifically to cater to that group? Doubtful.
That said, there's nothing keeping us from doing something... somewhat similar? The RPC chat has multiple room options marked as being for RP - and you can even make your own custom rooms (and password lock them if you want to do a private scene without someone barging in). So, while it's not a MUD, it's still another way to do RP without being in game... along with the Town Square section of these forums, and other external communication options like Discord and Skype (if anyone uses Skype anymore, of course).
The idea that SE would make a MUD, unfortunately, strikes me as horribly unfeasible.
