Okay, then wouldn't we then be calling whatever we can still see to be
the "early" universe? And therefore wouldn't we then be saying that the
universe is always 13.7 billion years, since that's as far out into
that we can see?

Why do you not think that in one billion years we will estimate
the age of the universe to be 14.7 billion years?

The restriction of observable horizon won't kick in for a while?

In the near term, our observable horizon is expanding about one
light-year every year.
