Your statement earlier holds true only if portions of the system are being
replaced. I was under the assumption the entire system was being replaced,
in which increasing diameter will not be more demanding.
And yes, there is more to calcs...

There is more to a calc than just pressure. Flow is also part. Why do you
think we are required to pick the sprinkler closer to the main on a tree
calc?

No, no, no. As long as you are increasing the ID along the primary
path, you are not making the calc more demanding. Increasing the ID
reduces the friction loss per ft. and reduces the overall required
pressure of the system.
