Um, I don't?

What about a real physical implementation of a Turing machine, where
rewiring it gives you different Turing machines?
True, you have to get the data onto the tape initially, but since that
wouldn't be part of the "program" per se, I don't see where that's addressed.

Not *now*, no. Back in Turing's day, that's exactly what it was. :-)
