For lack of a better description, not everyone shoots "equivalent DoF" priority all the time. Or even most of the time. The potential purchasers would likely shoot "I need more light" priority, and that's where this lens fits in.
If you're going to do the format compares, then you can pretty much strike out APS-C, since there is no 30-35mm f/1.2 which would be required if you maintain the equivalent aperture comparison. Even downgrading to a f/1.4 isn't cheap still. The full format may have a 50mm f/1.8, but you still need the full format sensor behind it, again not so cheap in any fair like for like comparison. And all that still neglects considerations outside of image quality.
Having said all that, I wouldn't get one either. The MF experience on Olympus at least just isn't there. If it had AF, it might raise some interest even if it the image quality isn't there wide open.
