I'm not convinced. I run a number of machines where that is pretty
much exactly what I want: in the presence of that kind of respawning
behaviour, whether from a fat-fingered command line or from some other
cause, taking the service down until a human has looked at it is
*exactly* what I want.
You appear to be coming from a mindset wherein availability is
everything: where an overloaded service is better than none at all, for
example. It's fine to accommodate such environments, but please don't
impose their idiosyncracies on the rest of us.

That's what it sounds like to me.

That is...well, false. It is exactly what I want, for example, for
most services on most of my machines: if something goes wrong (and the
syndrome in question here certainly counts) I want the service taken
down until a human can look at it. I would rather have an otherwise
functional system with that service missing than a system trying to
limp along overloaded, or with its log partition blown out by the
resulting error messages, or any of the various other consequences of
not taking down the failing service. Even if it's a deliberate DoS on
the service, for most services, I'd rather take the service down
pending human intervention.
These tradeoffs do not apply everywhere; I certainly do think it would
be good to avoid imposing them everywhere the way inetd currently does.
But I think it equally bad to do the converse: to impose some other
environment's tradeoffs here.

No, it doesn't mean that it's desirable. But you appear to be making a
leap of illogic from that to meaning it's undesirable.
