I'm trying to understand how this is more beneficial to web developers over the existing prefix approach.

As I understand it,

-moz-border-radius: 3px;
-webkit-border-radius: 3px;
-o-border-radius: 3px;

would simply be replaced with:

border-radius: 3px !moz-draft;
border-radius: 3px !webkit-draft;
border-radius: 3px !o-draft;
border-radius: 3px;

While visually more appealing, it doesn't seem to solve the problem that...

* prefixes/suffixes aren't dropped
* web developers will use an implementation before it's finalized
* web developers will target a specific browser without providing fallbacks to other browsers

If I misunderstood and that future implementations should actually ignore !suffixes such that we might see implementations like:

border-radius: 3px !moz !webkit;

…and simply have the suffixes ignored in final implementations, then I see some positives. 

* implementations that don't change between draft and rec will work without requiring web devs to update implementations.
* implementation changes can be localized with separate declarations (like prefixes are now).

Could you clarify the intent here?
