Clearly the problem is that we are passing in the "flags" param
from 2 different public APIs into the same internal method and
just blindly assuming all flags are equivalent. This is only
working by luck.

It is probably saner if the internal method has a "bool validate"
parameter and didn't use the public flags ?
