I'd vote for #2 as it would make possible things like that (a variant of
the use-case you mentioned):

 $rs->method_that_adds_a_calculated_column->search(
   ...
   {
      remove_columns => ['big_text_column'],
   }
 );  # and still have the calculated column (added via "+columns")

Also this behaviour is the less surprising: with #1 the behaviour of
'remove_columns' (or '-columns' or whatever it will be called)
would depend on whether a given column comes from the result source or
from a previous search() call.
