I think Zappa's wife considered the spirit in which Frank's wish was made. She recognized that it stemmed from care for her. She transmuted that into being an activist to protect his work and that made her happiest, which is really what Frank wanted. As for Einstein, bleah, he is not to be admired for his terrible treatment of his women and of one of his sons. So let his house remain in obscurity.
