Using a list in collection for cycling using an 'initial-value' ('default-value'
if that what most people would like it to be, is not an extreme case.

Will 'INITIAL-VALUE' be deprecated and made obsolete.  Then we would be using
'DEF' ?  One thing that bothers me quite a bit is the idea of obsolescence,
but in practice we keep things as they are for the sake of not breaking compatibility
with older versions.  The result is a complicated call definitions that while
they exist, a concurrent rule is actually in effect suggesting others what should
be used and not used.  

While providing multiple ways of accomplishing tasks can offer flexibility and 
accommodate various preferences and use cases, leaving conflicting or redundant
features leads to confusion and complexity for developers working with the codebase.

Deprecation should mean removing them in newer versions with instructions to developers
on migrating to the alternative.

Can there be the option to place an item from the collection (call it 'INITIAL', 'DEF', 'WHATEVER')
that appears as soon as `completing-read` is called ?
