For the time being, any deletion in a stylesheet always results
in a valid stylesheet. But if we have the following:

  @media .... {
     ...
  }
  @else {
     ...
  }

and if you remove the @media part, you end up with an invalid statement
(the standalone @else). All existing code, everywhere on the Web,
performing deletions in a stylesheet will need to be updated to care
for that.

Similarly, insertions in a stylesheet will have to do some validation
to avoid breaking @media+@else.
