A properly designed crowbar should be able to handle the current and

in the process, it's still doing it's job, but that is unlikely to
happen if foldback limiting occurs.

Actually, a Crowbar System ONLY needs to be able to blow the fuse,
or circuitbreaker that protects the LOAD from the overvoltage
condition that the Crowbar is monitoring. Protecting the supply
from overcurrent draw condition is the Foldback Current Limiter's
Job. Two completely different senerios.
