Zeroing in on this question, which does everyone prefer:

* "Binary clones" (in the sense of "one of two roles", but not very
obvious)

* "Stateful clones" (potentially confusing with anonymous vs unique
clones, and all resources have state)

* "Multistate clones" (less confusing with anonymous vs unique, and
already in current use in documentation, but still all resources have
multiple possible states)

* "Promotable clones" (consistent with "promote" theme, but the word
looks odd, and confusing with whether an individual instance is
eligible to be promoted)

* "Promotion clones" (also consistent, but sounds odd and not
particularly obvious)
