The *reason* to use 'Address and address clauses is to interface with
hardware. That's fine, but there aren't that many people writing such
interfaces. "No one" is a bit much, perhaps, but it should be way below 5%.
(If it isn't, that says Ada is way under-utilized.)
In any case, indexing always gets the right answer with the possible
exception of packed arrays. So there's not a lot of need or value to
following that Implementation Advice.
