I wasn't certain if, in order to utilize versioning later, that I
would need to mark the current model in some way. The Apple dox
didn't state one way or another, and I didn't wish to make an
assumption and find out later that I missed some important step which
would result in hours of headache.

So, my question is: is it better to create (start with) a
versioned model
to better facilitate the probable incidence of migration to a newer
model
later?
Short answer: No.
Why would you do that? In what way do you anticipate that it would
facilitate support for versioning in the future?
If you only have a single version, there's no point in creating a
versioned model -- you'd simply create a new version and then have
to delete it.
