Alan, you're missing the point.  The feature that the author wanted (e.g. box-shadow), which is all we're discussing:
* was originally documented as available only prefixed, so they write their pages using only the prefix;  it is as much an error to write unprefixed pages as unprefixed implementations
* at some point, a decision is made to document the stable unprefixed version, and allows its use
* you propose that the browser vendors then, at their next update, dump support for the prefixed version.  

All the existing uses of that feature (which is all we're discussing) then break, until the authors do an update.  Not acceptable.

Its evolution will be fine, if we manage the transition from vendor prefix, to shared prefix, to unprefixed, correctly.  It won't be if we dump pages that used to work, abruptly.
