The main reason why analogue equalizers are avoided nowadays (and rightly so) isn't phase distortion in the first place, but the bunch of electronics components in the signal path that all imprint themselves on the signal (likely in the form of harmonic distortion and modulation noise) – as Rob Watts sais: Every single electronics component reduces transparency, even cables and solder joints. Phase distortion is an inevitable by-product of any frequency-response distortion, and that also applies to existing nonlinearities e.g. in sound tranducers. So a perfectly inverse frequency-response distortion will recreate a perfectly linear phase response in addition to a linear amplitude response.
It's clear that parametric equalizers offer the better precondition than graphical equalizers for an equalization as perfect as possible, but the phase distortions produced by the latter are only half as harmful considering their still existing phase-response compensation capability. And BTW, once you see the real-world (acoustic!) phase response of a sound transducer, particularly headphone, you may ask yourself if it's worth caring about phase distortions of a magnitude as in (graphic) equalizers at all. The phase distortions produced by an unequalized headphone are much larger. Add to this that the audibility of phase distortions per se is disputed.
I for one can absolutely live with the octave equalizer in my FiiO X5 II and the ⅓-octave xnor/foobar equalizer for my DAVE for now. Does anybody know of a good parametric equalizer for foobar2000?
