Yeah, that should be either ERROR and return a void result, or issue a
WARNING/ERROR (depending on the code path, maybe PANIC?) with a
boolean status returned if there is a WARNING.  Mixing both concepts
with an ERROR all the time and always a true status is just weird,
because you know that if no errors are raised then the status will be
always true.  So there is no point to have a boolean status to begin
with.
