I'm not sure I understand what you're saying. Chrome showcased multiple innovations in browser technology. Things like a single process per tab, a much tighter security model, and proof that javascript implementations could be much faster. By doing this they have set trends in how browser technologies should progress and thus had an influence on their ability to implement "html 5" webapps in the future that work cross browser. It was much more than "check it out we put tabs in the title bar guys".
