The purpose of this API is basically to satisfy AMO reviewers in the future, since the use of innerHTML with variables (i.e., not plain text) will be rejected without any questions. Since this is not a problem for browsers other than Firefox, they will use simple innerHTML assignment, however safe-parsing could be implemented for them too.
