That would definitely be a problem if the compliance regulations were written based on existing technologies with insufficient flexibility to allow for buildings that are functionally and safety-wise equivalent but using technologies that didn't exist or weren't considered when the regulations were written. It's definitely the sort of thing that can slow down innovation, but it's not going to prevent it altogether. Regulation should never prevent developing proof-of-concept buildings and then being able demonstrate that they're just as good as those built with conventional technology, and building codes aren't carved in stone (even if they change at a seemingly glacial pace).
