I read Jason's reply as answering the concern about the stability of
the /rescue tools in that circumstance, not the trustworthiness of
dynamic linked applications in this case..
I.e, Johnny was concerned that /rescue can't be "trusted" with a
broken libc. Jason's comment is that a statically linked /bin
would be affected by the same issue, so it's a moot point.
