I'd say that is a feature, actually ... If only
ets:update_counter had the same behaviour (or _nearly_
the same: behaving _as_if_ the counter had value 0
before this operation).

I could then replace

  case catch ets:update_counter(Tab, Key, Incr) of
     {'EXIT',_} -> ets:insert(Tab, {Key, Incr}), Incr;
     N -> N
  end

with (the silently initializing version):

  ets:update_counter(Tab, Key, Incr)

Pretty please, someone? :-)

Best,
Thomas
