The only reason these two functions are still around is that at some point in the past they were in a public header, so we can't really remove them now even though they should have been private all along (and aren't really particularly useful). Since these are just empty stubs now that do nothing but return FALSE and will be removed in 0.11 anyway, we may just as well deprecate them formally.
