It's not hacking to remove a font. It more like editing. It's real easy to do in Calibre. I have it set to remove all user fonts, margins and colors. I still use the old mobi format. KF8 doesn't work with the Personal Documents Cloud yet.
Actually, it's not KF8 being a new format that's the problem. Most KF8 started life as an ePub. Very few KF8 actually started life as KF8 code.
That being said, even if KF8 was not originally ePub, the same font mistakes would be made. I've taken embedded fonts that did not look good enough on eInk and found a medium or semibold version to use in place. Or I've fattened it up myself. Some have too much line space so I've had to adjust the line-height. Cannot do that with KF8. But you can adjust the font's line space and then keep that modified font in case any other eBooks use it.
