Support for EPS is highly unlikely, since EPS doesn't support RGB color spaces very well (it has mainly been geared towards print media). So it would require converting the RGB color space to a more bland CMYK color space, rendering any bright colors to a less brilliant approximation. That's a big no-no !
And EPS has a lot of trouble handling 'soft' transparancies natively, like shadows, blurs and even simple opacity levels. So the EPS needs to "flatten" all vector based transparant effects to a bitmap. (This is also happening for the regular PDF, but only in case of background blurs.) Another hindrance for EPS support.
Why or what would you need EPS for ?
Who is requesting this (legacy) format ?
