It would be valuable to mark the default entry
when users scroll through the options defined
for `completing-read` whenever a DEF is supplied.

I'm not sure what you mean.

Is this about highlighting in `*Completions*' a
completion that's the DEF?

Suppose one moves through the collection. There is no way

that identifies the entry as being a designated DEF.

Is it about selecting (as the active region) the
DEF value when you insert it with `M-n'?

I think M-n ensured you are refering to DEF.

Something else?

And is the request to be able do whatever-it-is
_optionally_ or always?

Optionally is ok, but do not know the technical details. I do not think

doing it always would be a bad thing.
