No, it is a design issue.  POV-Ray cannot know if focal blur will be enabled
in a later frame as it reparses the scene each time.  However, it cannot
know if antialiasing was on or off once it has been turned off automatically
after focal blur has been used.  Practically using focal blur together with
antialiasing is illegal, so it has to do something.  I agree that the
"something" is not logical, but turing on and off focal blur in different
frames is simply a very rare case, so nobody ever noticed this missing
feature...
