If I explicitely tell my system to load a ramdisk, ignoring it is a bug.

I had a similar bug in PAM: One of these modules has a parameter to invert
the check. I copied the tested configuration to an old debian system, which
did not have this parameter, and it decided to ignore it (as if I were just
joking while writing the config files of a security system). Therefore the
system was open for everybody who was not supposed to use it.

I don't think ignoring an intrd will be as serious, but having a panic (and
a timeout) is preferable to starting the wrong configuration.
