Comment (by Nikschavan):

 I agree with @obenland on not updating the default themes concerning the
 backwards compatibility, Although I am not too sure if I like the
 deprecated notice being displayed on the front end to all the visitors of
 the site.

 Maybe only show the notice to logged in/ admin users? or add the notice in
 `error_log()`?

 Either way, as we are planning to not to patch the themes, user who has
 this theme installed will have only two options to get rid of this warning
 either to change the theme or downgrade WordPress both the options are not
 good.
