No, because the use now would be the use then which is not really vestigial.
The blueprint was not sketched yet for the building.
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.

vestigial
A structure in an organism that serves little to no use. Vestigial structures are degenerated and range from slightly harmful to useless to slightly useful. They are remnants of an organism's evolutionary past.
Humans: the appendix, wisdom teeth, and ear muscles are examples of vestigial structures. Whales: hip bones and hind limb remnants are vestigial structures in whales. Pythons: pelvic spurs, remnants of hind limbs, are vestigial structures in pythons.

Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
