It does add a lot of weight and complexity. If I am not mistaken today’s pattern plans have stoped using retracts.
Complexity yes, weight, not so much. Classic pattern planes of the 80’s were often 8-9 lbs and hauled the mail with a piped 60/61. I can build the same and come out under 8 lbs (with retracts).
