Don't feel special. Nobody reads anybody elses posts. That's why there are answers to questions not asked, and suggestions for solutions when the solution is already posted.
That's not what happened here. There are also questions that are asking for add solutions or looking to overcome obstacles that really shouldn't be there.
For new construction on an improperly roughed door, the path of least resistance would typically be to make two cuts with a reciprocating saw, pull some wood out, and make the frame true to what it should be.
If everyone were to "answer the mail" in all situations, many posters would be left spending more money and wasting more effort to get a worse outcome. <- So that type of thing wouldn't be too helpful.
I guess it's good that in this particular application, the OP doesn't mind having a small door, but on most structures built after 1930, walking through an exterior door less than 36" would feel really off.
