Yes.
It is easier to register the negatives on a light table with a loupe and
tape them together.
It is much quicker and easier to expose the coating with only one
negative sandwich.
Time between multiple exposures and registration may allow the coating
to accumulate or loose moisture.
It is more convenient to adjust the negatives as I am already accustomed
to working with masking. This includes adding densities rather than
adding light.
Further, being able to build each negative properly, I see no reason or
advantage to go the route of multiple exposures.

There is no image degradation due to the thickness of the sandwich using
a paper like Crane's Cover-90 and a bank of BLB bulbs.
