One thing I cannot readily determine from the documents is whether one

versioned from the start as opposed to later in the application's life
cycle.
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.
