Well the patch doesn't exists yet. If I do the patch as I original
thought this is possible by doing a 'FREECIV_CAPS="+1.11.6 conn_info
pop_cost turn attributes" ./civ -t trident'. Another way is to change:
void init_our_capability(void)
{
  char *s;

  s = getenv("FREECIV_CAPS");
  if (s == NULL) {
    s = CAPABILITY;
  }
  sz_strlcpy(our_capability_internal, s);
+ if(want_sno)
+    sz_strlcat(our_capability_internal, " sno");
}

So I see no problem of disabling this.
