My entire library is in standard epub format, and I'd rather not convert them; I find it surprising that the feature can't be added for epubs.
My guess is it's a little bit of both.

As AnemicOak said, there are two renderers involved and the surrounding application to present them. For epubs, the Adobe RMSDK is used. From comments made in a couple of places, I think that interacting the RMSDK is not the most pleasant thing to do. It's possible they can't do something like the image zoom, it's hard enough to make it not worthwhile. But, there is probably an element of having function that is available for kepubs only. Whether that meant they didn't look at implementing it for epub, or discovered it was hard or impossible and decided not to do it, I don't know.
