It certainly will be overwritten if there is a new version of libsane-hpaio or, for that matter, if that package is reinstalled. Making a backup of an existing file after changing it isn't really necessary. A new version of models.dat would likely include data for newly supported devices, as happens with libsane-hpaio from stretch backports. -- Brian.
