I don't think I'd use the word "only". On the other hand, it's
plausible that "reliability" has quite different meanings for, say,
video-on-demand and banking. For some applications, predictable
jitter is more important than exactly-once semantics. If I'm
sending sensor readings, cheap but lossy may be just fine.
Etcetera. In practice, a relatively small number of patterns
is likely to emerge, with associated ontologies and semantics.

It's worth looking at how systems like JMS (Java Messaging
Service) coped with the problem of abstracting quality
of service (including reliability).
