read-key-sequence does use current-active-maps, not sure about
menubars and toolbars (what code is that?)

Fread_key_sequence
  return read_key_sequence_vs (prompt, continue_echo, dont_downcase_last,
read_key_sequence_vs
  i = read_key_sequence (keybuf, ARRAYELTS (keybuf),
read_key_sequence
  current_binding = active_maps (first_event);
active_maps
  return Fcons (Qkeymap, Fcurrent_active_maps (Qt, position));
