DRC in the bass would be nice. Above the bass I see RC as a strategy with a kind of negative feedback loop. The more you focus on complete correction the more likely the correction might be distorted by random variabilty. I see this all the time on FR plots done with impulses and mics, there is something like a tooth comb pattern overlaying the general shape of the FR curve. Correcting for these tiny variations is usually futile because their exact position and size tend to vary on each measurement. That's just FR, but RC tries to correct a lot more. Another way of saying it is that IMO a lot of what is corrected by RC is in a fashion noise. As opaqueice stated at higher frequencies there is a lot of chop and change within small distances. It doesn't make sense to correct this kind of thing at a particular point. That is why many RC systems allow you to soften the filter so it works over a larger area but no so starkly. My point is that this limitation is inherent to the DSP endeavor - it isn't just a feature of implementations of DSP technology.
That's why I like to use warble tones to do my FR curves. They smooth the picture FR-wise, and FR-wise humans perceive the smooth picture and filter out those random fluctuations. That's why I believe there is no total solution possible with RC. It can help, for some listeners, but I don't agree it is a silver bullet that with enough work can cure all. In the bass it works a treat and opaqueice wrote some explanations also as to why. I am more for taking the 'natural' approach first. If that doesn't work or isn't possible then DSP is the next port of call, by all means.
