[erlang-questions] callback module without behavior definition?

One thing that has bothered me about implementing gen_servers is that I have
to create empty stubs for the callbacks that I don't need.  Today I made a
gen_server that only needs init/1, so instead of creating all those stubs I
just commented out the behavior definition "-behavior(gen_server)."

It seems to work fine, and the compiler doesn't complain.  Are there any
consequences to not having a behavior definition that I am overlooking?  My
whole module looks something like...

-export([start_link/0, init/1]).

start_link() ->
  gen_server:start_link(?MODULE, [], []).

init(_) ->
  {ok, []}.

My actual use-case here is to have a gen_server that "holds" a named,
read-only ets table for other processes to read.  init/1 creates the table
and loads data, and process termination makes the table go away.
