FWIW I think this is bad advice.

Services are only "internal" to the extent that you can trust your network.
Search "SSL added and removed here" for a practical demonstration of this
assumption yielding undesirable results.

Disabling hostkey checking is a big hammer, but occasionally useful for
lab environments. Generally I recommend that people who are having trouble
with hostkey management consider using host certificates.
