I understand your concern, but it is effectively, virtual room correction... fairly common. Corrective EQ can be a huge help, WHEN DONE JUDICIOUSLY AND CORRECTLY WITH THOUGHT FOR WHAT ISSUE YOU ARE ADDRESSING. There's no point in trying to correct a midrange comb filter at the mix position caused by a short path difference reflection. It will be narrow and keep moving as you shift your head (or the mic) by just a few inches. This is actually one area where "intellegent" multiple placement testing can verify what issues should be addressed and which ones shouldn't. There's also no point in trying to add back in 10dB at some LF dip caused by modal or SBIR issues... These are judgements that an experienced room tuning professional can make easily, but any automatic corrective software has to be well thought out as well as well programmed to handle.
At the end of the day, it all comes down to knowing what you're doing with any playback system EQ. General smoothing and response sloping can be greatly beneficial in my opinion... almost all else is most likely as destructive, (if not more) than helpful UNLESS you really understand what issue; acoustic, speaker response, placement, reflections... etc. you are addressing.
Hope this makes sense...
