Sorry, but aliases are not deferred labels.
We use an alias to disambiguate between properties.
I don't think we have anything that is equivalent to DCterms coverage,...
At least I hope not!
An alias does not imply equivalence, not by a long shot.

You asked for an example, end those are valid

example that use one of the most used ontologies on the net. Other
examples from DCterms is coverage, which can be both temporal and
spatial. We have a bunch of properties that can have an alias "DCterms
coverage", a country for example or a year.
For cross-linking properties with other vocabularies, we use P1628 "Equivalent
Property", not aliases. I don't see how an alias would be useful for that.
P1628
allows you to specify URIs, and it is itself marked as equivalent to
owl:equivalentProperty, so it can be used directly by reasoners.
Use a separate list of "deferred
labels", and put the existing label
on that if someone tries to edit the defined (preferred) label. That
list should be unique, as it should not be possible to save a new
label that already exist on the list of deferred labels. At some
future point in time it can be implemented some clean up routine, but
I think it will take a long time before name clashes will be a real
problem.
That's the idea, yes, we just call the deferred labels "aliases".
