We're supposed to jump through hoops to ensure backwards compatibility with RMSDK’s broken error parsing–which certainly isn’t ePub2 compliant–but prefixed properties are supposed to be a problem?

Also, ADE 4.5 does support several webkit-prefixed properties. I have successfully used -webkit-column-break-after for page breaks and -webkit-initial-letter for drop caps. The standard "initial-letter" is not supported.
Because it's spreading incorrect information.

There is a way around the older RMSDK's CSS bug. Use @support for any CSS that causes RMSDK to ignore the CSS. The other issue is that there are a lot of Readers out there in use that use an older RMSDK that does not support webkit. For example, Kobo uses some version 3 RMSDK and they are current Readers that are used by a lot of people. Some still use a Sony Reader which uses an even older RMSDK.
